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 »

The trade winds are caused by a combination of convection air currents and the Earth's rotation. Air is warmed near the Equator and moves towards each pole, respectively. This air is deflected by the Coriolis effect, or ... 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 »
