What is the Weather?

     Weather is what is happening in the atmosphere now, at any place on Earth’s surface. It includes the temperature, precipitation (rain), wind and clouds, among other components. A weather forecast is a prediction of weather conditions over a particular area.

     We study the weather to help people plan what to wear, when to travel, and when it is safe to be outdoors. Weather forecasts prepare the public for severe weather, such as a hurricane or tornado. Weather is also important for pilots before, during, and after flights. Sometimes an accurate forecast may mean the difference between life and death.

Climate, on the other hand, is quite different than weather. It is the common, average weather conditions at a particular place
over a long period of time (for example, about 30 years).
We learn about different climates around the world -- such
as the hot and dry climate of deserts, or the extremely frigid and dry climate of the Antarctic. 

Weather has a profound effect on our lives and we always can discover new things about the different types of weather -- which include: 

- The Sun: the main source of energy that drives the weather, providing light and heat. We get seasons because the Earth revolves around the sun.

- Clouds: a fundamental part of our weather; they are made up of billions of water and ice particles floating in the sky that often-times produce rain, snow, hail or sleet. Fog is a cloud that is on ground level.

- Rain: a very important type of precipitation that falls from the clouds, as it provides water to drink, to wash our cars, and water the grass. Rain also keeps large bodies of water (rivers, lakes, etc.) at a stable level, thus protecting the animals and fish that live in these environments. 

- Severe weather: has the potential to harm us and the environment via floods, hurricanes, tornadoes, thunderstorms, and blizzards -- to name a few.
