Every day, thousands and thousands of people tune into weather forecast on television, radio, even news papers for information about the weather in case any changes are going to happen in the forthcoming days and nights, like floods or droughts or temperatures change. Meteorology is the study of all changes in the atmosphere, whether they were changes in temps, air pressure, dampness, or wind way in the troposphere. The environment around the planet earth is called the atmosphere, it is split into layers. Weather happens in the troposphere, underneath layer, directly above the ground. Mount Everest, the best point on the planet earth, reaches about half way the troposphere. Meteorology is useful for weather operations and forecasting.
Meteorology is the science of the atmosphere. It originates from the Greek term "meteoron", this means something that happens saturated in the sky. Weather was important to the early Greeks because it damaged the farmers who increased their vegetation and their seamen who sailed the oceans. The historical Greeks seen and tried to understand how the clouds, wind flow, and rain were connected one to the other.
Weather is an endless cycle of occurrences. The four things that cause weather are the Sun, the atmosphere, normal water vapor and the wind flow. They all interact, spreading the Sun's heat around the globe and making clouds. Plus the changes that arise over a longer time frame are known as local climate. Weather is definitely a significant concern to humans, and our incapability to control it includes led us to attempt to assess it, compare it, and forecast it for days gone by more than 100 years. Weather contributes greatly with the study of meteorology, the five major weather elements are:
The sun is the primary source of energy for the earth. The light and high temperature provided by sunlight make it possible for crops and animals to go on earth. Without the sun, oceans would freeze and life could not be supported on the planet. The sun is the key to the earth's weather. It goes the air worldwide creating winds which carry weather changes. Air temperatures is measured with a thermometer. http://images. google. com/url?source=imgres&ct=tbn&q=http://library. thinkquest. org/J0112188/sun_and_earth. gif&usg=AFQjCNH7-leVbgPcZpt29YvgoD3Yoo8NqQ

Although air is light, there may be so much of it that air can exert huge pressure on earth. Air pressure or atmospheric pressure is triggered by the weight of all air pressing down everywhere at the bottom. Air pressure changes when the temps changes, it differs from spot to place and every once in awhile as the Sun's temperature varies. Regions of high pressure are produced where air is sinking down, so it's forcing harder towards the planet earth. However when air goes up it leaves behind a location of lower pressure, because upwards moving air is not pushing down so hard on the surface this creates low pressure. Air pressure is assessed in millibars, mb, on a barometer. Barometers help us forecast weather because changes in air pressure are associated with changes in the weather.
There are various kinds of moisture. Moisture is present in the air either by means of gas, water, or sound. Atmospheric moisture takes on a significant role in weather when it changes in one point out to the other. Warm air can hold more water than chilly air can. A hygrometer may be used to measure humidness, which is the quantity of drinking water in the air. A hygrometer consists of a damp bulb and a dry bulb thermometer. One end of the moist bulb thermometer is covered with muslin, which is damp. If the air is dried up, more drinking water will evaporate and the moist bulb thermometer will show a low reading.
Air public are huge people of air which are warm, cold, damp, or dry depending on the land or sea they go by. Air people move all over the Earth's surface, they help propagate the Sun's heating throughout the world. Air people are classified in line with the area or the foundation they originated from.
There are two types of air public. Air public that form over oceans and seas called maritime. We've Tropical maritime, which advances over warm seas, and Polar maritime, forms in the seas near the poles. Air masses that form overland are called continental; there is Exotic continental, air mass that advances over hot or dried up land, and Polar continental, air mass that develops over land near to the poles.
Boundaries between air people are called fronts. The elements can be very unsettled near the fronts; some frosty fronts cause lines of violent storms. You can find three types of fronts, warm, frigid, and occluded.
Wind is moving air. It blows because some air public become warmer than others, in essence wind moves as a result of difference in air pressure about the world. In heated air, the tiny allergens of air disseminate. Scores of heated air is lighter when compared to a mass of wintry air, because warm air is so light it goes up. As heated air rises, chilly air flows in to take place. Local climate and weather are dependant on the wind. Wind is also influenced by the Coriolis Result. The earth spins on its axis, in the north hemisphere winds are swung to the right. And in the southern hemisphere winds are swung to the left, this is called the Coriolis Impact. A windsock is used to gauge the wind quickness and course. A weather vane may also be used to look for the wind's course.
Violent storms can be very dangerous, but as we find out more about the elements it becomes better to forecast violent storms to avoid disasters. Some severe climate are thunderstorms, tornadoes, hurricanes, and avalanches. Some extreme weather conditions such as floods and droughts may also affect the weather in some areas.
Thunderstorms sometimes happen when the environment is humid and warm. Clouds form in the sky and blustery winds begin to blow, thunderstorms usually include lightning followed by thunder. Lightning and thunder happen at exactly the same time, but you see thunder first because light vacations faster than sound.
Tornadoes are long funnels of violently spiraling winds. They form on land when you can find warm, damp air near the ground and frosty, dried up air above it. The Coriolis Effect helps the tornado spin faster, as well as plane streams when they move outrageous of the storm.
Weather forecasting is the application of research and technology to forecast the status of the atmosphere for a future time and confirmed location. The most straightforward way to anticipate the elements is to simply look out the windows. However, for a far more correct weather forecast you will need observational tools like radars, satellites and specially designed personal computers that will give you a clearer picture to the weather conditions.
Some weather symbols that are being used in television forecast and maps:

Good harvests is determined by good weather, early on farmers who resided about 7, 000 years back thought gods ruled the weather. Customers still pray for fine weather and good harvest.
The Rainbow God, the Kabi folks of Australia worship a god called Dhakhan who is half snake and half fish. He looks as a rainbow in the sky when he goes from one hole to another.
The Dragon Breath, the Chinese language presumed that dragons formed clouds with the breath and brought rain. The rainwater dropped when the dragons walked in the clouds and storms raged when they fought.
Dancing in the Rain, the Hopi Indians of THE UNITED STATES perform special rainfall dances, and pray to the gods through these dances to send them rainwater.
The father or creator of meteorology is known as to be Aristotle. His book "Meteorologica" written around 340 B. C was the first research of the atmosphere. Some of Aristotle's ideas were accurate, like ideas about rainfall and hailstorms, others weren't. Like many thinkers of his time, he assumed that reason and reasoning could lead to the reality and he didn't think it was necessary to observe the details of the natural world to comprehend it; that's why he got some of his ideas proven incorrect in old age.
As years went by, many decades later natural philosophers realized that reasoning and speculation arguments together couldn't produce real understandings of the natural world. For them to understand things in the world around them, it was necessary for them to measure, record, and analyze. But at that time, really the only things that might be measured were wind flow path and rainfall. And it extended like that for years to come. Later around A. D 1600 the thermometer was invented, following that the barometer, which actions atmospheric pressure, emerged a couple of years later. Devices and gadgets for measuring blowing wind speed, moisture, and other important attributes of the atmosphere extended to develop over another two- hundred years. Scientists used all of these newly-created tools to record the permanent trends of the elements that happen to be known as environment. However, they still didn't understand your day to day or daily tendencies of weather trend like tornadoes, hurricanes, and thunderstorms.
Years continuing to pass, by the mid- 1800s, meteorologists started to realize clouds, wind flow, and rain at a particular place are produced by large weather systems that grow and change as they move. However these details was not very helpful so long as weather information couldn't travel fast enough. The telegraph was later invented, allowing weather reports to be sent out instantly. Then they started to realize a few of the weather patterns across the face of the earth. In the first 1900s, a group of Norwegian meteorologists began to review weather systems through the use of basic laws and regulations of physics to the tendencies of the atmosphere. There finding or approach predicated on moves of huge warm and cool air masses and where they meet is the building blocks of modern weather forecasting. Inside the 1940s, World Warfare II helped bring great innovations in the analysis of meteorology. Armed service land, sea, and air campaigns were highly reliant on weather over vast parts making its way from the North Pole to the South Pacific. Meteorology departments in colleges grew quickly as the military services delivered cadets to learn as weather officers. The military also supported methodical research on the elements and climate. During this period, technological developments including the radar proved to be useful and valuable meteorological observing systems for both armed service and studies coping with meteorology.
Meteorologists continued to develop a lot more new tools and techniques, since World Conflict II, for observing and learning the atmosphere. They developed numerical model sets of equations that stand for atmospheric techniques and run them on supercomputers to analyze and forecast the tendencies of the atmosphere on every scale from the forming of raindrops to the blood circulation of the atmosphere over globe. Meteorologists today use satellites to see hurricanes; they probe the violent cores of thunderstorms with radar and high performance aircrafts and many more

More than 2, 000 years ago, Greek philosophers looked at the sky and attempted to understand what was occurring there. Today, the traditional research of meteorology is continuing to grow and matured. It is at the cutting edge of research, seeking answers to basic questions about the entire world all around us. Meteorologists today use satellites to see hurricanes; they probe the violent cores of thunderstorms with radar and powerful aircrafts. They will work to help expand more develop applications that are crucially important to our lives and the lives of our kids and the many more years of grandchildren yet to come.
