Wind blows due to air-pressure gradients that are the result of the uneven heating of the Earth's atmosphere. Prevailing winds blow in a consistent direction over large areas of the Earth's surface, while local winds are... More »

Strong winds are most often caused by air moving from an area of high atmospheric pressure to an area of low pressure quickly over a small distance. This is called a strong pressure gradient force. More »

The uneven heating of the Earth's surface creates hot and cold spots, creating the potential for convective currents. Air above a warm spot rises, creating a low pressure zone near the surface. Colder, denser air near th... More »

Wind energy is created when moving air causes a wind turbine to rotate, powering a motor that generates electricity. The energy of the wind itself derives from differential heating of the air by the sun and the rotation ... More »

Wind speed is the rate or movement of air flow as it travels from high to low pressure, in relation to the Earth. Warm air rises because it weighs less than cold air, and the cold air then moves in and replaces the warm ... More »

Wind is created by the uneven heating of Earth's surface and atmosphere. Different substances on the planetary surface absorb solar radiation at different rates. Warmer air expands to create a pressure difference that pr... More »
