Wind Power

What is Wind? Wind is the movement or flow of gaseous elements around earth surface. One of the most important characteristics of wind is its velocity. Another characteristic of wind is energy. It is affected by high and low pressure of air of that particular location or area. Earth surface is heated randomly by the sun which depends on the occurrence of sun ray's angle and surrounding of the land. Sun ray's angle can be varied with latitude and time of day. Water of the oceans heat up and cool down slowly in comparison to land. Heat energy which is absorbed in earth's surface is transferred to air directly above these oceans and lands. The density of warmer air is less in comparison to cooler air. These factorsarecreating constantly changing characteristics of wind across earth's surface.
