Wind Notes 10.26.11
-When infared radiation from the Sun hits the surface of the Earth the temperature of the surface will change.
-Air is not warmed by the sun's rays. It is warmed as it comes in contact with the ground or water. Warm air is less dense than cold air. Since air is a fluid the warm air is pushed up by the cold air.
-This process, called convection, causes warm air to rise and cold air to sink.
-When warm air rises it created a low pressuer area. When cool air sinks it creates a hight pressure area.
-Air will be pushed away from the high pressure area to the low pressure area.
The horizontal movement is called wind. Winds can be local or cover large areas of land.
