Climate Change and Weather Essay

Climate Change and Weather Essay.

The term weather describes the state of the air at a particular place and time – whether it is warm or cold, wet or dry, and how cloudy or windy it is, for example. It affects many of the things that we do, from the clothes we wear and the food we eat, to where we live and how we travel. As a result, the weather is of great interest to people everywhere, from meteorologists, the scientists who study it in great depth, to you and I in our everyday lives.

In fact, one of the main topics of conversation is often what the weather will do next the . Weather is very changeable and unpredictable.

What is Climate? The normal pattern of weather experienced in a particular area over a long period of time is known as the climate. The climate tells us how hot, cold or wet it is likely to be in different parts of the world at different times of year.

For example, tropical countries have hot climates and the Antarctic has a cold climate. The climate may include four seasons a year – spring, summer, autumn and winter – or a wet and a dry season. Our climate depends on our position on the earth and our distance from the sun. We will learn more about this in the Days and Seasons section.

What is weather forecasting? Weather experts use computer technology and data from stations and satellites all over the world to predict the weather. By carefully monitoring weather conditions it is possible to predict when change is due – what we know as weather forecasting. What is Climate Change? Climate change refers to any significant change in the measures of climate lasting for an extended period of time. In other words, climate change includes major changes in temperature, precipitation, or wind patterns, among other effects, that occur over several decades or longer.

What is Global Warming? Global warming refers to the recent and ongoing rise in global average temperature near Earth’s surface. It is caused mostly by increasing concentrations of greenhouse gases in the atmosphere. Global warming is causing climate patterns to change. However, global warming itself represents only one aspect of climate change. Climate change is happening Our Earth is warming. Earth’s average temperature has risen by 1. 4°C over the past century, and is projected to rise another 2 to 11. 5°C over the next hundred years.

Small changes in the average temperature of the planet can translate to large and potentially dangerous shifts in climate and weather. Rising global temperatures have been accompanied by changes in weather and climate. Many places have seen changes in rainfall, resulting in more floods, droughts, or intense rain, as well as more frequent and severe heat waves. The planet’s oceans and glaciers have also experienced some big changes – oceans are warming and becoming more acidic, ice caps are melting, and sea levels are rising.

As these and other changes become more pronounced in the coming decades, they will likely present challenges to our society and our environment. Who is Responsible? Over the past century, human activities have released large amounts of carbon dioxide and other greenhouse gases into the atmosphere. The majority of greenhouse gases come from burning fossil fuels to produce energy (Charcoal), although deforestation, industrial processes, and some agricultural practices also emit gases into the atmosphere.

Greenhouse gases act like a blanket around Earth, trapping energy in the atmosphere and causing it to warm. This phenomenon is called the greenhouse effect and is natural and necessary to support life on Earth. However, the build-up of greenhouse gases can change Earth’s climate and result in dangerous effects to human health and welfare and to ecosystems. There other elements of people’s homes that contribute to climate change indirectly. Everything, from furniture to computers, from clothes to carpets, all use energy when it is produced and transported – and this causes carbon emissions to be released.

The choices we make today will affect the amount of greenhouse gases we put in the atmosphere in the near future and for years to come. Women as the face of Climate change Women make up a shocking 70 percent of people living in poverty around the world. The gender imbalance of climate change is about more than just numbers, though. During natural disasters and extreme storms — of which many are increasingly linked to our carbon-loaded atmosphere — women often lack the physical strength needed to pull themselves to high ground or to run for safe cover.

If this physical barrier isn’t enough, women are usually responsible for children and relatives and in extreme conditions; they have the added burden of moving everyone out of harm’s way. Furthermore, they face social, economic and political barriers that limit their coping capacity. Women and men in rural areas in developing countries are especially vulnerable when they are highly dependent on local natural resources for their livelihood. Those charged with the responsibility to secure water, food and fuel for cooking and heating face the greatest challenges.

Secondly, when coupled with unequal access to resources and to decision-making processes, limited mobility places women in rural areas in a position where they are disproportionately affected by climate change. It is thus important to identify gender-sensitive strategies to respond to the environmental and humanitarian crises caused by climate change It’s this universal role as caregiver — one that we would rarely change if given the chance — that increases women’s vulnerability to our changing climate. With motherhood comes the responsibility of providing food, water, shelter, protection and transportation for children.

In a warmer world, these are increasingly challenging tasks. It is important to remember, however, that women are not only vulnerable to climate change but they are also effective actors or agents of change in relation to both mitigation and adaptation. Women often have a strong body of knowledge and expertise that can be used in climate change mitigation, disaster reduction and adaptation strategies. Furthermore, women’s responsibilities in households and communities, as stewards of natural and household resources, positions them well to contribute to livelihood strategies adapted to changing environmental realities.

Effects of climate change on women Climate change has serious ramifications in four dimensions of food security: food availability, food accessibility, food utilization and food systems stability. Women farmers currently account for 45-80 per cent of all food production in developing countries depending on the region. About two-thirds of the female labour force in developing countries, and more than 90 percent in many African countries, are engaged in agricultural work.

In the context of climate change, traditional food sources become more unpredictable and scarce. Women face loss of income as well as harvests—often their sole sources of food and income. Related increases in food prices make food more inaccessible to poor people, in particular to women and girls whose health has been found to decline more than male health in times of food shortages Furthermore; women are often excluded from decision-making on access to and the use of land and resources critical to their livelihoods.

For these reasons, it is important that the rights of rural women are ensured in regards to food security, non-discriminatory access to resources, and equitable participation in decision-making processes. In the rural areas, women and men are highly dependent on biomass, such as wood, agricultural crops, wastes and forest resources for their energy and livelihoods. However, in the face of climate change, the ability of women and men to obtain these indispensable resources is reduced.

It is important to note that the declining biodiversity does not solely impact the material welfare and livelihoods of people; it also cripples access to security, resiliency, social relations, health, and freedom of choices and actions. To give a few examples, declining fish populations have major implications for artisanal fishers and communities that depend on fish. Moreover, in many parts of the world, deforestation has meant that wood – the most widely used solid fuel – is located further away from the places where people live.

In poor communities in most developing countries, women and girls are responsible for collecting traditional fuels, a physically draining task that can take from 2 to 20 or more hours per week. As a result, women have less time to fulfil their domestic responsibilities, earn money, engage in politics or other public activities, learn to read or acquire other skills, or simply rest. Girls are sometimes kept home from school to help gather fuel, perpetuating the cycle of disempowerment.

Moreover, when environmental degradation forces them to search farther afield for resources, women and girls become more vulnerable to injuries from carrying heavy loads long distances, and also face increased risk of sexual harassment and assault. Climate change has significant impacts on fresh water sources, affecting the availability of water used for domestic and productive tasks. The consequences of the increased frequency in floods and droughts are far reaching, particularly for vulnerable groups, including women who are responsible for water management at the household level.

All over the developing world, women and girls bear the burden of fetching water for their families and spend significant amounts of time daily hauling water from distant sources. The water from distant sources is rarely enough to meet the needs of the household and is often contaminated, such that women and girls also pay the heaviest price for poor sanitation In terms of health, some potential climate change scenarios include: increased morbidity and mortality due to heat waves, floods, storms, fires and droughts.

What’s more, the risk of contracting serious illnesses is aggravated by environmental hazards caused by climate change. In addition to the reference provided above of climate impacting women’s health through water scarcity and water contamination, an abundance of evidence links the evolution and distribution of infectious diseases to climate and weather.

Four areas have been identified as critical building blocks in response to climate change: mitigation, adaptation, technology transfer and financing Mitigation involves a process of curbing greenhouse gas emissions from human activities, for example emissions from fossil fuels as well as deforestation, with a view to stabilizing greenhouse gas concentration at a afe level Adaptation is adjustment or preparation of natural or human systems to a new or changing environment which moderates harm or exploits beneficial opportunities, it involves a range of activities to reduce vulnerability and build resilience in key sectors, such as water, agriculture and human settlements. New and improved technologies and financing initiatives at all levels also need to receive attention as part of collective efforts to address climate change There is the need to recognise the importance of placing women at the heart of sustainable development.

It would be a mistake to solve the climate change impacts without integrating women in the process, or improving their status and economic empowerment since women’s management of local natural resources is crucial. Thus: * Improving women’s economic status is a key element in reducing the impact of climate change on women—this is an imperative given the fact that women have direct connection to locally based natural resources. One of the key components of global action on climate change should be measures to adapt to changes that are already unavoidable.

Women must find another means of making a living. * The education of women on the impacts of climate change on their socio-economic activities as well as the provision of extension services to women farmers on appropriate technological innovations, improved storage facilities and resource management services are recommended. Governments are urged to give women an equal say in how funds given to poor countries to help them adapt to climate change, are managed and spent.

This can be by improving education and healthcare choices for women. Improved access to clean fuels would have profound effects not just on the prosperity and health of individual families, but more broadly on the developing countries they live in. Keeping a lid on population growth, in particular, would also allow developing nations – which make up 80 per cent of the world’s overall population – but which consume only 20 per cent of the world’s energy resources and contribute 30 per cent of the world’s greenhouse gases to have a say in global debates on dealing with the impact of climate change. Reinvesting in long-term, renewable, clean energy (wind, geothermal, sun, cellulosic ethanol. thus protecting threatened forests.

These common sense solutions won’t only reduce global warming; many will save us money and create new business opportunities. * Financing mechanisms must be flexible enough to reflect women’s priorities and needs. The active participation of women in the development of funding criteria and allocation of resources for climate change initiatives is critical, particularly at local levels.

Gender analysis of all budget lines and financial instruments for climate change is needed to ensure gender-sensitive investments in programmes for adaptation, mitigation, technology transfer and capacity building. In summary Women can be more affected by climate change, but they can also be agents of change in their communities and in their families. Women can push to be more organised in their communities around common issues. Therefore, women’s participation can ensure that problems are solved more creatively. A step ahead for women can be equivalent to a leap for mankind.

What Are Heat Waves Essay

What Are Heat Waves Essay.

A heat wave is a prolonged period of excessively hot weather, which may be accompanied by high humidity. While definitions vary, a heat wave is measured relative to the usual weather in the area and relative to normal temperatures for the season. Temperatures that people from a hotter climate consider normal can be termed a heat wave in a cooler area if they are outside the normal climate pattern for that area. What are the symptoms of heat strokes and sunstroke?

Heat stokes: * high body temperature – a temperature of 40°C (104°F) or above is often a major sign of heatstroke, although it can be diagnosed at lower temperatures and some people can reach these temperatures during physical exercise without developing heat exhaustion or heatstroke * heavy sweating that suddenly stops – if the body is unable to produce any more sweat, it’s a major warning sign that it has become over-heated and dehydrated * a rapid heartbeat * rapid breathing (hyperventilation) * muscle cramps Sun stoke: Hot and dry skin, rapid heartbeat and pulse, sweating stops, rapid breathing, increase in body temperature, muscle cramps, headaches, nausea, confusion and dizziness.

Heat exhaustion is fatal but heatstroke can be.

Other potential problems include: sun burn, redness and pain in the skin. In serve cases there are also swelling blisters, fevers and headaches.

How to avoid problems in a heat wave? * Increase your intake of non-alcoholic, non-carbonates, caffeine, free beverages, such as water and fruit juice. * Wear clothing that is light in colour and loose fritting. * Avoid he outdoors during extreme heat * Stay out of the sun * Stay in an air conditioned environment

Who is most at risk of a heat wave? * The elderly and young are very vulnerable to effect of high temperature. * Obese people and those with medical conditions such as heart disease and diabetes are also at high risk. * However anybody could be at a risk if they did not take sensible steps

Use of Satelite Technology for Weather Forecasting Essay

Use of Satelite Technology for Weather Forecasting Essay.

Weather forecasting is the application of science and technology to predict the state of the atmosphere for a given location and over the years many techniques have been used to forecast the weather, Satellite technology is one of it. The history of weather forecasting and early satellite programmes was told using archive film, highlighting the difficulties associated with a lack of weather data. Two hundred dedicated weather satellites have been launched since the 1960s. Together, these satellites enable us to monitor every weather system around the world and to see the weather as it approaches.

Weather prediction can save lives, especially in tropical regions as information from satellites is used to track hurricanes as they develop. The first satellite completely dedicated to weather forecasting was developed by NASA. The satellite was named TIROS-I (television and infrared observation satellite) and was launched on 1st April, 1960.

The weather satellite is a type of satellite that is primarily used to monitor the weather and climate of the Earth.

Satellites can be polar orbiting, covering the entire Earth asynchronously, or geostationary, hovering over the same spot on the equator. Meteorological satellites see more than clouds and cloud systems. City lights, fires, effects of pollution, auroras, sand and dust storms, snow cover, ice mapping, boundaries of ocean currents, energy flows, etc., and other types of environmental information are collected using weather satellites. Weather satellite images helped in monitoring the volcanic ash cloud from Mount St. Helens and activity from other volcanoes such as Mount Etna. Smoke from fires in the western United States such as Colorado and Utah have also been monitored. Other environmental satellites can detect changes in the Earth’s vegetation, sea state, ocean color, and ice fields. Weather satellites carry instruments called radiometers (not cameras) that scan the Earth to form images.

These instruments usually have some sort of small telescope or antenna, a scanning mechanism, and one or more detectors that detect either visible, infrared, or microwave radiation for the purpose of monitoring weather systems around the world. The measurements these instruments make are in the form of electrical voltages, which are digitized and then transmitted to receiving stations on the ground. The data are then relayed to various weather forecast centers around the world, and are made available over the internet in the form of images. Because weather changes quickly, the time from satellite measurement to image availability can be less than a minute. Most of the satellites and instruments they carry are designed to operate for 3 to 7 years, although many of them last much longer than that. Weather satellites are put into one of two kinds of orbits around the Earth, each of which has advantages and disadvantages for weather monitoring.

The first is a “geostationary” orbit. Geostationary weather satellites orbit the Earth above the equator at altitudes of 35,880 km (22,300 miles). Because of this orbit, they remain stationary with respect to the rotating Earth and thus can record or transmit images of the entire hemisphere below continuously with their visible-light and infrared sensors. This allows the satellite to view the same geographic area continuously. The news media use the geostationary photos in their daily weather presentation as single images or made into movie loops. For instance, GOES-East and GOES-West provide coverage of much of the Western Hemisphere, from the western coast of Africa to the West Pacific, and the Arctic to the Antarctic. The European Space Agency’s Meteosat satellite provides coverage of Europe and Africa. The disadvantages of a geostationary orbit are:

(1) Its very high altitude, which requires elaborate telescopes and precise scanning mechanisms in order to image the Earth at high resolution (currently, 1 km at best); and (2) only portion of the earth can be viewed. The other orbit type is called near-polar, sun-synchronous (or just “polar”), where the satellite is put into a relatively low altitude orbit (around 500 miles) that carries the satellite near the North Pole and the South Pole approximately every 100 minutes. Unlike the geostationary orbit, the polar orbit allows complete Earth coverage as the Earth turns beneath it. Polar orbiting weather satellites offer a much better resolution than their geostationary counterparts due their closeness to the Earth.

The world’s first polar weather satellite system, referred to as TIROS operational system (TOS), became a reality in the year 1966 with the launch of ESSA-1 and ESSA-2 satellites, on 3 February 1966 and 28 February 1966 respectively. These orbits are “sun-synchronous”, allowing the satellite to measure the same location on the Earth twice each day at the same local time. Of course, the disadvantage of this orbit is that the satellite can image a particular location only every 12 hours, rather than continuously as in the case of the geostationary satellite. To offset this disadvantage, two satellites put into orbits at different sun-synchronous times have allowed up to 6 hourly monitoring.

But because of the lower altitude (500 miles rather than 22,000 miles), the instruments the polar-orbiting satellite carries to image the Earth do not have to be as elaborate in order to achieve the same ground resolution. Also, the lower orbit allows microwave radiometers to be used, which must have relatively large antennas in order to achieve ground resolutions fine enough to be useful. The advantage of microwave radiometers is their ability to measure through clouds to sense precipitation, temperature in different layers of the atmosphere, and surface characteristics like ocean surface winds. Because of their global coverage, some of the measurements from polar orbiting satellites are put into computerized weather forecast models, which are the basis for weather forecasting. Today, many countries of the world other than the USA have their own weather satellite systems to monitor the weather conditions around the globe. These include China, Japan, etc.

The NY Times reports that some experts say it is almost certain that the U.S. will soon face a year or more without crucial weather satellites that provide invaluable data for predicting storm tracks. Which apparently was the birthplace of weather satellites. This is happening because the existing polar satellites are nearing or beyond their life expectancies, and the launching of the next replacement. So the replacement of satellites is also an important issue to be considered for any country. Over the years even India has launched many weather satellites one of which was launched recently in October 2012, which was India’s maiden satellite mission to decode monsoon and climate changes, in which its polar rocket successfully put an Indo-French satellite into orbit that also proved its reliability for the 19th time in a row.

So due to inherent advantages of monitoring from space, coupled with advances in sensor technology, satellites have brought about a revolution in weather forecasting. The end result is that there is a reliable forecast of weather and other related activities on a routine basis. With the help of these satellites even pollution whether it’s nature-made or man-made can be pinpointed. The visual and infrared photos show effects of pollution from their respective areas over the entire earth. Aircraft and rocket pollution, as well as condensation trails, can also be spotted. The ocean current and low level wind information gleaned from the space photos can help predict oceanic oil spill coverage and movement and all the information can be easily found out.

Winter vs. Summer Essay

Winter vs. Summer Essay.

The four seasons are the way mother nature lets us know she can’t make up her mind on what food, clothes and activities she likes. Winter, spring, summer and fall, each, in their own way, affect various aspects of our lives. Specifically, Summer and Winter have extremes which determine change our life during those few months. Sometimes, people’s daily activities, habits and style of life change as the seasons vary. I personally, believe that winter offers a lot more comfort than summer and is overall a better season for food, activities and clothes.

The type of food people consume varies during summer and winter. In summer, because the weather is so hot, people would prefer to eat cold food like ice-cream to keep them cool, in the hot sun, Kids, for instance, sell ice cold lemonade, because it counters the heat of the summer. However, during winter, people will prefer to eat hot and spicy food which would help them to keep themselves warm like hot soups and stews.

I love the idea of warming myself up with a nice bowl of homemade soup and cuddling up by the fire. Just as ice cream is sold during summer months, restaurants serve soup during winter months. It is rare that anyone would want a glass of lemonade when there is snow outside, rather they would enjoy a piping hot mug of hot chocolate.

People’s way of dressing also tends to change because of the different seasons. During summer people will usually wear casual clothes like t-shirts, shorts, dresses and sleeveless tops to keep them cool. Accessories, at that time, would include sunglasses and flip-flops because they cater to the conditions outside. On the other hand, during winter, people will normally wear thick and warm clothes which are the most appropriate attire to keep themselves warm. Boots, gloves, coats and hats are the main accessories at the time. Colors also tend to vary during the different seasons. Summer is associated with bright and sunny colors, whereas winter tones are typically darker and duller. Winter clothes are much more flattering and offer a wider variety of styles for every type of trend.

There are also different types of activities that can be carried out during summer and winter. Summer is the time where people will usually go traveling and it is also the best weather for outdoor activities. The beach is one place that is hopping in the summer with all ages of people because everyone wants to soak up the sun, go swimming and get a great tan before it’s too cold. Generally, kids are outside more during the summer, playing baseball, swimming or just enjoying the beautiful weather.

During winter, there are a large amount of sports that can only be played when there is snow. For example, skiing, snowboarding, and ice skating are strictly winter sports. Instead of family time being spent at the beach, it is spent in a ski lodge with a nice warm fire. Although it requires a lot more layers, kids can still go play outside in the winter, making snowmen and having snowball fights. In my opinion, there is nothing better than playing in the snow then going inside for some hot chocolate; You can’t get comfort like that at the beach. There are possibilities for fun and family time in any weather condition.

Many aspects of life are affected by the changes in season. Particularly, winter and summer portray the various extremities that are apparent during those months. While summer offers sun and fun at the beach, all in all, winter has so much more to offer in terms of food, clothing and activities.

Worst Day Ever Essay

Worst Day Ever Essay.

It was a one fine morning. The sun rose steadily, peeking through the curtain and illuminating Ian’s room beautifully as the sixteen-year-old boy was still deep in his slumber. Even the shrilly sound of the annoying alarm clock did not wake him up. It continued for about thirty minutes before Ian was greeted with ice-cold water on his face and body. Slowly, he opened his eyes and the realization sank in as soon as he saw his mother’s face.

Judging from his mother’s facial expression, he knew that he was late to school again. He muttered a loud sorry to his mother as he darted to the bathroom for a quick shower. His mother could only shake her head at her son’s behaviour. Ian let out a painful moan when the steaming hot water hit his body. He backed away, trying to turn off the hot shower at the same time. Unfortunately, he burned his skin a few times before he finally succeeded.

Finally, he gave up on showering and started to head down to catch up with the last bus to his school. As weird as it sounded, Ian had a bad feeling that it was going to be his worst day ever.

Everything seemed wrong from the very start. First of all, he began his day late as he woke up late for school that day. So here he was, chasing after the bus which already on its way with its loyal morning passenger all aboard. Ian knew that it was a futile attempt because once the bus had moved away from the bus stop; there was no way to stop it. He plopped down lazily on his buttock on the cold chair in the bus stop. His stomach was grumbling because he missed his breakfast as a result of waking up late. His mother won’t let him have even just a small bite of those delicious home-made pancakes of hers. Ian glanced down at his red wristwatch, it read 8.01am.

Sighing out of frustration, he decided that it would be best if he started walking to school. As he walked, he muttered some incoherent curse words under his breath, unaware of the presence of a large, black dog creeping up soundlessly behind him. The next thing he knew was that he was running for his life, trying to get away from the scary dog. Unfortunately for Ian, luck was not on his side that day. His bag was bitten by the fierce dog, causing it to tear apart. His paper and homework were scattered all over the road. Though it was hard to admit, it was indeed the worst morning ever for Ian.

As soon as he reached his school, everyone was mad at him. It looked like everybody decided to get mad at him that day. He was punished by the security guard for trying to climb the closed school gate. Even though Ian himself knew that it was wrong to just climb the gate like that, he was desperate and he knew that he was going to get more problems if he was any later that he already was. He received a scolding from the guard before he was off the hook. The worst part of it was the fact that he injured his leg as he fell down from the gate just now.

Drowning himself in his own misery, he had to limp all the way to his class, wincing every now and then at the painful throbbing feeling in his left ankle. It did not get better once he arrived at his class. He knew that things like this were bound to happen when he turned up late in class. Ian was scolded by the strictest teacher in the school whom he had a class with for the first two period of the morning. It was all due to his missing homework. Cursing his bad luck, Ian remembered the incident with the rabid dog earlier. He looked sadly at his torn bag as he willingly accepted the punishment that the teacher had in store for him. As a punishment, he had to run around the school field. In short, his day could not get any worse with everybody getting angry with him.

Finally, worst had come to the worst as the weather too was not on his side that day. Dark clouds started to gather on the once flawless blue sky. It started to rain heavily while he was running around the field. The ground was slippery and he knew that he had to be more careful with his steps. His hurt ankle was not much of a help as it only contributed to him, feeling worse than ever. When the throbbing feeling on his leg became unbearable, he decided to stop. Unfortunately, as soon as he stopped running, he accidentally tripped over a big stone that came out of nowhere in the middle of the field. Expecting what was going to come next, he closed his eyes as he fell into a big puddle of thick mud.

The rain did not show any indication that it was going to stop so Ian decided to rest under a big tree at the side of the field. He certainly did not see this coming. He was completely taken aback when the lightning struck the tree that he was resting under. He ran quickly to save his life. The harsh lightning burned the tree. It was a narrow escape from the tree but unluckily, he burned some of his hair. He walked away from the tree with such a sad back, silently crying over his bad luck for the day. Thus, the bad weather completed his worst day ever.

Ian would never forget that day when everything went wrong. The suffering and hardship that he went through that day shall always be remembered. Even though it was a bad memory, he wanted to treasure that one fragment of his life forever. It was indeed the worst day ever.

  1. Single cell and supercell thunderstorms.

Single cell thunderstorm takes place in the late afternoon, when temperature is the hottest and usually takes place in the summertime, whereas supercell thunderstorm usually takes place after midnight. Air mass thunderstorm is caused by convective lifting (it means that because of high temperature and heating during the day some quantity of warm air raises, although they can be of different temperature and different humidity. So, when this cloud reaches the point where the difference of temperature is enough to condense, it creates a cumulus cloud (this is a cumulus stage), the second stage is mature stage, where this condensed accumulated water vapor becomes large and then after it results into ice particles and heavy droplets, which fall down as rain.

In case the temperature in the upper atmosphere is cold enough, it can even fall down as hail.

Sometimes, in case there are both downdrafts and updrafts during this stage, it can cause some movements which result in lightings, strong winds and even tornadoes.

And, finally there is dissipation stage), whereas supercell thunderstorm can be caused both by convective and frontal lifting (they take place when updrafts form cumulo-nimbus clouds, then after there is a mesocyclone, which results more dangerous and windy storm). Single cell thunderstorms are not so dangerous like supercell thunderstorms, which can be single cells or can be formed of a number of cells either and can be spread over several states.

  1. Lightning stroke sequence.

So, lightning mostly starts with charge transfer in cloud (where positive and negative charges are formed – it begins usually with a local discharge which frees electrons that were attached to ice particles or water. The electrons neutralize small positive charge of the base of the cloud and continue their way to the ground), followed by a stepped leader (these electrons move in luminous steps approximately 50 yards long) which reaches to the ground (and when the leader approaches the ground, there takes place a large positive charge below it and) and connects with upward-moving discharges approximately 30-50 meters long. When the contact is done, there is a violent discharge to the ground. Light is produced mainly by the return stroke, which we usually call the lightning. This process can be repeated, starting with a dart leader, because usually flashes contain several strokes.

  1. Tornado formation.

The first condition for having tornado is a supercell thunderstorm (warm tropical air, which is moist, meets together with cold polar air, which is dry). When a mesocyclone becomes stronger, it enlarges downwards. Simultaneously, it becomes more compact so it starts to swirl with higher speed, forming a kind of funnel creating an area with very low pressure, which absorbs more air). In case this process will continue, this mesocyclone can reach the earth and result a tornado. Because of this funnel of very low pressure, there is a danger the funnel will suck not only air inside, but even some tings from the ground (parts of buildings, people, some small things, etc).

  1. Effects of hurricanes in human environments.

Damage caused by hurricanes is great. It can be losses of life and damage of property. For example, the 1935 Labor Day Hurricane where 600 people died, and 1969 Hurricane Camille, which caused damage of 1,4 billion dollars. The Bay of Bengal (1970) hurricane resulted approximately 300 000 people death. Agnes Hurricane of 1972 caused major flooding which became even a tropical storm and caused other damage as well.

Cameran Highlands is about a 3 hours drive either from KL or Penang Its strategic location makes it a favourite weekened escape for cityfolk/ city-dwellers from all over the coutry. It is a popular haunt for both local and foreign tourists to let their hair down. For those who are faint-heated the ride along the steep, narrow roads can be quite an unnerving experience as there are numerous hairpin bends along the route from Simpang Pulai.

After about a three-hour ride in Dad’s Pajero, we finally reached Kampung Raja. We could feel the goose-pimples on our arms. We had to put on our jackets to keep ourselves warm. Standing about 1400 metres above sea level, this hill resort is certainly an ideal retreat for city dwellers like us who long to get away from scorching tropical heat. Besides, its high altitude together with its invigorating coolness will leave a person refreshed and is the ideal place for the rat-race and the hustle and bustle of city life.

On our journey to Tanah Rata, we stopped at a scenic lake. Although the chilly weather and freezing water will make us to think twice about whether or not to don our swimming wear, we can enjoy the solitude of nature with only the swish swashing of the gurgling water to disturd us. Thus, in spite of the cold weather, my little sister, my brother and I could not resist the urge to jump into the water and splash around. Hardly a minute in the ice cold water and we were out again, teeth chattering. At Tanah rata, we checked into a motel. As soon as we had dumped our luggage in our rooms, we went out again. The street in which our motel was situated had a fine vista of a sprawling town against a backdrop of lush greenery. At that moment , We felt ravenously hungry, Hence, we settled for a sumptuous meal of nasi kandar.

Undeniably, the number of eateries that have sprung up is indeed alarming. Satiated, we turned in for the night. We put on the appropriate gear and headed for Gunung Beremban for an hour of jungle-trekking. Hikers will certainly enjoy traversing the jungle paths, for they are well-maintained and easy to follow. If you find the jungle trails a little monotonous, the blossoms of brightly coloured wild flowers along the way will provide an interesting diversion. My mother, who is extremely afraid of heights, was soon down on all fours, not daring to look down and yelling at the top of her voice. It was such a rib-tickling sight. Our next destination was a tea plantation.

As an enormous wall of gray clouds approaches, the anticipation grows ever so slightly with each passing moment. This warm sun-filled afternoon slowly begins its descent into a cool breezy evening as the rain commences. A few tiny droplets fall from the dark canopy above onto the carpet of green blades beneath my feet. Across the wavy pasture the verdant pine trees at the woods’ edge come alive as they sway back and forth like stalks of wheat from some lonely field in rural Nebraska.

A thin layer of fog slowly begins to form just above the warm ground as the steady downpour continues.

My brother and I were as close as any two siblings could be. Although he is a full three years older than me, we seemed to do more together than he and the guys his own age did. We could fish for hours and hours, although we didn’t usually catch much except for loads of weeds and algae.

We knew that snagging a few bass wasn’t primarily the purpose of our trips to the pond. The outings were our refuge; we could completely forget about how much we hated school or all the problems we had with girls and just laugh over his dirty jokes and my embarrassing stories while the fish paid no real attention to our bait.

We both also shared an unquenchable thirst for rainstorms. Most people think of rain as a nuisance that upsets the normal rotation of sunny cloudless days and causes usual outdoor activities to be put on standby, but not to Brian and I. As soon as we noticed the wind picking up or a sudden drop in the temperature, we would head for the pasture. Nature seems to take on a completely different kind of beauty when it rains, a beauty truly appreciated by both of us. One day as the rain was falling, Brian and I decided to sit underneath our giant old oak tree, as we sometimes did, to eat a few apples and talk about our day. As I went to retrieve some more fruit, a deafening boom that sounded as if a bomb had hit directly behind halted me. As I turned, I saw the old oak split in half and Brian lying on the wet ground.

I come here every August fourth (Brian’s birthday) to place a flower next to the white cross that stands where the old tree used to. For six years I haven’t let a drop of precipitation touch my skin. When I first arrived here today there wasn’t a cloud in the sky. Now I stand immersed in all sorts of emotions as I place a vibrant orange tiger lily next to the cross. As I begin to walk away, the steady downpour ends just as suddenly as it had began. I’m not bothered.
