Wind is the movement of air across the surface if the Earth from areas of high pressure to areas of low pressure. The surface of the Earth is heated unevenly by the Sun depending on factors such as; the angle of incidence of the sun's rays at the surface (which differs with latitude and time of day) and whether the land is open or covered with vegetation. Also large bodies of water, such as the oceans, heat up and cool down more rapidly than the land. The heat energy absorbed at the Earth's surface is transferred to the air directly above it and, as warmer air is less dense than cooler air, it rises above the cool air to form areas of high pressure and thus pressure differentials. Also the rotation of the Earth drags the atmosphere around with it causing turbulence. Both these effects combine to cause a constantly varying pattern of winds across the surface of the Earth.
