Global winds



Global winds are winds that blow steadily over a long distance. Blows from the same direction every time

how are they are created?

LIke local winds, global winds are created by the unequal heating of eaths surface, but unlike local winds global winds occur over a large area.

The coriolis effect makes winds in the Northern Hemisphere curve to the right, and it makes the winds in the Southern Hemisphere curve to the left


*Are located around/on the equator

*It refers to those parts of the Atlantic Ocean and the Pacific Ocean

* A low-pressure area around the equator where the prevailing winds are calm.

Trade winds

The trade winds are the prevailing pattern of easterly surface winds found in the tropics, within the lower portion of the Earth's atmosphere, in the lower section of the troposphere near the Earth's equator.

Prevailing westerlies

Prevailing westerlies are the winds in the middle latitudes between 35 and 65 degrees latitude. They tend to blow from the high pressure area in the horse latitudes towards the poles. These prevailing winds blow from the west to the east steering extratropical cyclones in this general manner.

Jet streams

A jet stream is a very cold, fast-moving wind found high in the atmosphere. Jet streams are so fast and powerful that airplanes have difficulty flying against them. Pilots either fly with the jet stream or above it; they do not attempt to fly against it.
