The “force” ex-erted by the wind is a function of the wind speed as well as the swept area of the wind turbine’s ro-tor. The “distance” is the height of the tower. As swept area (force) or wind speed (force) increase and tower height;

Because the Coriolis force is proportional to the rate of turning of the earth's surface, relative to which air speed is determined, it increases with latitude. Mathematical analysis shows that it is Above two or three thousand feet the friction force, (1) As friction decreases with height, wind speed increases;

Temperature Profiles: The change of air temperature with height above the ground. Troposphere: The layer of the atmosphere from the Earth's surface up to the tropopause, characterized by decreasing temperature with height, appreciable vertical wind motion and considerable water vapour content.

The height of the wind above the earth’s surface also affects the average wind speed. Frictional drag and obstructions near the surface of the earth generally retard wind speed and induce a phenomenon known as wind shear (the change in a wind’s speed with elevation).

Wind speed and direction respond to pressure gradient forces that exist between and because of the rotation of the earth, winds circulate in a clockwise In addition, colder temperatures near the poles generally are associated with earth's surface and rapidly decreases with height (within lowest 1 km).

A method and apparatus for altering at least one selected region which normally exists above the earth's surface. The region is excited by electron cyclotron resonance heating to thereby increase its charged particle density.

The factors that influence wind-speed generally also influence direction. The statistical variation of wind-speed and direction can be graphically represented by a wind rose (see Map 06). Because of the friction between wind and the earth's surface, the wind-speed increases with height above ground level.
