What Is Meteorology And Its Uses Environmental Sciences Essay

What Is Meteorology And Its Uses Environmental Sciences EssayEvery day, thousands and thousands of people short letter into die hard account on television, radio, even give-and-take written reports for news approximately the support and if any changes argon going to take rear in the upcoming days, exchangeable floods or droughts or temperature change. Meteorology is the submit of all the changes in the tune, whether they were changes in temperature, stress nip, moisture, or booster cable guardianship in the troposphere. The subscriber line around the earth is called the line of descent, it is divided into layers. digest happens in the troposphere, the bottom layer, localizely above the ground. Mount Everest, the highest point on the Earth, reaches about half way up the troposphere. Meteorology is useful for go processes and forecasting.What is meteorology?Meteorology is the science of the atmosphere. It comes from the Greek word meteoron, which means some(a)thi ng that happens high in the sky. go was principal(prenominal) to the antiquated Greeks because it affected the farmers who raised their crops and their seamen who sailed the oceans. The ancient Greeks sight and tried to understand how the clouds, wander, and rain were connected to one another. hold outWeather is an checkless cycle of events. The four things that cause weather ar the Sun, the atmosphere, water supply vapor and the wind. They all work together, fan outing the Suns heat all all everywhere the world and making clouds. And the changes that occur everywhere a longer time period of time ar know as climate. Weather has always been a significant concern to humans, and our inability to control it has led us to savor to whole step it, comp be it, and predict it for the past hundreds of old age. Weather contributes greatly with the register of meteorology, the five major weather elements are-Temperature -Wind-Humidity - printing press-RainfallThe SunThe sun i s the master(prenominal) spring of energy for the earth. The light and heat given out by the sun make it possible for plants and animals to live on earth. Without the sun, oceans would freeze and smell could not be supported on earth. The sun is the key to the earths weather. It moves the manner all over the world causing winds which carry weather changes. propagate temperature is standardd by a thermometer. http//images.google.com/url?source=imgresct=tbnq=http//library.thinkquest.org/J0112188/sun_and_earth.gifusg=AFQjCNH7-leVbgPcZpt29YvgoD3Yoo8NqQhttp//library.thinkquest.org/J0112188/sun_and_earth.gif picnic PressureAlthough billet is light, there is so much of it that communicate can handle huge pressure on earth. Air pressure or atmosphericalal pressure is cause by the weight of all the air pressing bring in all steerings at the ground. Air pressure changes when the temperature changes, it varies from luff to place and from time to time as the Suns heat varies. Area s of high pressure are multifariousnessed where air is sinking down, so its pushing harder towards the earth. But when air rises it leaves behind an area of depresseder pressure, because upward moving air is not pushing down so hard on the surface this creates commencement pressure. Air pressure is broadsheetd in millibars ,mb, on a barometer. Barometers booster us forecast weather because changes in air pressure are linked to changes in the weather.Air MoistureThere are several(a) forms of moisture. Moisture is present in the air either in the form of gas, liquid, or solid. Atmospheric moisture plays a significant role in weather when it changes from one state to the other. Warm air can underpin more water than iciness air can. A hygrometer can be utilise to measure humidity, which is the amount of water in the air. A hygrometer consists of a wet bulb and a dry bulb thermometer. One end of the wet bulb thermometer is covered with muslin, which is wet. When the air is dry, more water pull up stakes evaporate and the wet bulb thermometer will show a low reading.Air MassesAir the vulgar are huge lower classes of air which are heartily, cold, moist, or dry depending on the dry land or sea they pass by. Air grasses move all over the Earths surface, they help spread the Suns heat around the world. Air masses are classified according to the area or the source they came from.There are two types of air masses. Air masses that form over oceans and seas called maritime. We turn in equatorial maritime, which develops over warm seas, and diametrical maritime, forms over the seas near the poles. Air masses that form overland are called continental there is Tropical continental, air mass that develops over hot or dry land, and Polar continental, air mass that develops over land near the poles.Boundaries between air masses are called fronts. The weather can be very doubtful near the fronts some cold fronts cause lines of violent storms. There are three ty pes of fronts, warm, cold, and occluded.WindWind is moving air. It blows because some air masses become warmer than others, basically wind moves because of the difference in air pressure around the world. In warm air, the tiny particles of air spread out. A mass of warm air is lighter than a mass of cold air, because warm air is so light it rises. As warm air rises, cold air flows in to take place. Climate and weather are determined by the wind. Wind is besides affected by the Coriolis Effect. The earth spins on its axis, in the northern hemisphere winds are swung to the right. And in the southern hemisphere winds are swung to the left, this is called the Coriolis Effect. A windsock is utilize to measure the wind speed and explosive charge. A weather vane can also be apply to determine the winds direction.Severe/Extreme weather conditions savage storms can be very dangerous, but as we discover more about the weather it becomes easier to forecast violent storms to avoid disasters . few implike weather conditions are thunderstorms, tornadoes, hurricanes, and avalanches. Some extreme weather conditions such as floods and droughts may also affect the weather in some areas.Thunderstorms on occasion happen when the air is humid and warm. Clouds form in the sky and bullying winds start to blow, thunderstorms usually include lightning followed by thunder. Lightning and thunder happen at the same time, but you see thunder first because light travels windy than survive.Tornadoes are long funnels of violently spiraling winds. They form on land when there is warm, moist air near the ground and cold, dry air above it. The Coriolis Effect helps the tornado spin faster, as well as jet streams when they pass over the top of the storm.Weather forecastWeather forecasting is the application of science and technology to predict the state of the atmosphere for a future time and a given location. The most unreserved way to predict the weather is to simply look out the wind ow. However, for a more accurate weather forecast you need observational tools like radars, satellites and specially designed computers that will give you a clearer picture to the weather conditions.Some weather symbols that are utilise in television forecast and mapshttp//images.google.com/url?source=imgresct=tbnq=http//s3.amazonaws.com/momentville/20889/photos/917979/917979_medium.jpgusg=AFQjCNHD4U47mTTE3a_bIXFBUrhjDKaQhttp//s3.amazonaws.com/momentville/20889/photos/917979/917979_medium.jpgWeather godsGood harvests depends on good weather, primordial farmers who lived about 7,000 years ago thought gods ruled the weather. People at present still beg for fine weather and good harvest.The Rainbow God, the Kabi people of Australia worship a god called Dhakhan who is half snake and half fish. He appears as a rainbow in the sky when he moves from one hole to the next.The dragon Breath, the Chinese believed that dragons formed clouds with their breath and brought rain. The rain fel l when the dragons walked over the clouds and storms raged when they fought. bound in the Rain, the Hopi Indians of North America perform special rain dances, and pray to the gods through these dances to send them rain.HistoryThe father or founder of meteorology is considered to be Aristotle. His book Meteorologica written around 340 B.C was the first subject area of the atmosphere. Some of Aristotles ideas were accurate, like ideas about rain and hailstorms, others were not. Like more thinkers of his time, he believed that earth and logic could lead to the truth and he didnt think it was infallible to lionize the details of the natural world to understand it thats why he got some of his ideas proven wrong in later years.As years went by, more centuries later natural philosophers derived that logic and speculation arguments alone couldnt adduce real understandings of the natural world. For them to understand things in the world around them, it was necessary for them to measu re, record, and analyze. But at that time, the only things that could be measured were wind direction and rainfall. And it continued like that for years to come. Later around A.D 1600 the thermometer was invented, following that the barometer, which measures atmospheric pressure, came a few years later. Devices and gadgets for measuring wind speed, humidity, and other important qualities of the atmosphere continued to develop over the next two- hundred years. Scientists utilise all of these newly-created meanss to record the long term trends of the weather which are known as climate. However, they still didnt understand the day to day or everyday behavior of weather phenomenon like tornadoes, hurricanes, and thunderstorms.Years continued to pass, by the mid- 1800s, meteorologists began to realize clouds, wind, and rain at a particular place are produced by large weather systems that grow and change as they move. However this education was not very useful as long as weather stud y couldnt travel fast enough. The telegraph was later invented, allowing weather reports to be sent out instantly. Then they started to realize some of the weather patterns crossways the face of the earth. In the early 1900s, a group of Norwegian meteorologists began to study weather systems by applying basic laws of physics to the behavior of the atmosphere. There discovery or approach based on movements of huge warm and cold air masses and where they meet is the foundation of modern weather forecasting. In the 1940s, creation War II brought great advances in the study of meteorology. armed services land, sea, and air campaigns were highly dependent on weather over huge regions making its way from the North Pole to the South Pacific. Meteorology departments in universities grew rapidly as the soldiery services sent cadets to be deft as weather officers. The military also supported scientific explore on the weather and climate. During this period, technological developments su ch as the radar prove to be useful and valuable meteorological observing systems for both the military and studies dealing with meteorology.Meteorologists continued to develop many more new tools and techniques, since World War II, for observing and studying the atmosphere. They developed numerical model sets of equations that read atmospheric processes and run them on supercomputers to analyze and predict the behavior of the atmosphere on every scale from the formation of rain roves to the circulation of the atmosphere over earth.

Today, the ancient science of meteorology has grown and matured. It is at the cutting edge of research, seeking answers to basic questions about the world around us. Meteorologists today use satellites to observe hurricanes they pr obe the violent cores of thunderstorms with radar and high performance aircrafts. They are functional to further more develop applications that are crucially important to our lives and the lives of our children and the many more generations of grandchildren yet to come.
