Weather is the daily state of the atmosphere, or air, in any given place. Climate is the average of weather
conditions in an area over a long period. The weather is important to people. It affects their comfort, their food
supply and even their safety.
Elements Of Weather

Many different elements combine to create weather. Temperature, he warm or cold it is outside, is one of
the fundamental elements of weather. Wind, or the movement of air across Earth's surface, is a second element
of weather. Winds may be gentle or powerful. A third element of weather is humidity, or the amount of
moisture in the air. Warm air can retain more moisture than cold air can. Precipitation, the fourth element of
weather, may come in many forms, including rain, hail, sleet and snow. The form precipitation
takes varies based on other weather conditions, such as temperature. A fifth element of weather is atmospheric
pressure, the weight of air above a given area. Changes in pressure help people to predict approaching storms.
A storm is a disturbance in the atmosphere-for example, a thunderstorm or a hurricane.
Meteorology
The scientific study of weather is called meteorology, and people who study and predict weather are called
meteorologists. Meteorologists use many instruments to gather information about weather. The thermometer
and the barometer are some of the oldest and most common weather instruments. The thermometer measures
temperature, and the barometer measures atmospheric pressure. Atmospheric pressure, also called barometric
pressure, is the weight of the air as felt at any given spot on Earth. Another common instrument is the wind
vane, which shows the direction in which winds are blowing. Today satellites in space collect weather
information worldwide. Computers help meteorologists to analyze weather patterns and make
weather forecasts
