Wind“Wind” is defined as the horizontal movement of air.
Air moves out of areas of higher pressure into areas of lower pressure.Unequal heating of Earth’s surface generates these pressure differences.Solar radiation, therefore, is the ultimate energy source for most wind.
Wind is controlled by a combination of forces, including:the pressure-gradient force
the Coriolis effectfriction
Isobars are lines that connect places of equal air pressure.The spacing of isobars indicates the amount of pressure change over a given distance
and is expressed as the “pressure gradient.”
WindThe Coriolis effect is also a participant in controlling the wind.
This effect is an apparent deflection in the wind direction
due to the Earth’s rotation.
Deflection of the wind is to the right in
the Northern Hemisphere and to
the left in the Southern
Hemisphere.

Finally, friction acts to slow the air’s movement near
the surface.
WindUpper level winds generally blow parallel to isobars, and are called geostrophic winds.The Jet Stream is a “river” of air at high altitude with a velocity of 120–240 kilometers per hour.
