MOVEMENT IN THE ATMOSPHERE
The Earth is a rotating sphere. The atmosphere, as well as the
hydrosphere (oceans and large lakes), move because of this rotation.
There is a difference between local and general worldwide winds. General
winds include those that stretch thousands of miles over the Earth's
surface with almost permanent directional patterns. Local winds are
characteristic of particular geographical regions and exert a pronounced
influence on the local climate.
The pattern of the general wind circulation is primarily determined
by the unequal heating of the atmosphere at different latitudes and
altitudes and by the effects of the Earth's rotation (Coriolis effect).
The general wind pattern includes doldrums, jet stream, polar
easterlies, trade winds, and westerly winds.
