Winds Jaime snyder p:7

Global warming

The globe is encircled by six major wind belts. The global wind pattern is also known as the"general circulation". The sufarce winds are divided into three wind belts.

Global convection currents

All winds are caused by the uneven heating of the Earth's surface that sets convection currents in motion. Convection currences are somewhat caused by local winds.

Global Wind Belts

Global Wind Belts are winds that blow in belts encircling the planet. The belts circle the whole world and can vary from 60-90 degrees latitude in polar easterlies.


Doldrums is a area at the equator with no winds. The Doldrums are located in parts of the Atlantic and Pacific Ocean.

Horse Latitudes

Horse Latitudes are subtropical latitudes between 30 and 38 degrees. Located in the north and south where Earths atmosphere is dominated.

Trade Winds

Trade Winds are winds blowing steadily toward the equator from the northeast in the northern hemisphere.

Prevailing Westerlies

Prevailing Westerlies are winds from the west toward the east in the middle latitudes between 30 and 60 degrees.

Polar Easterlies

Polar Easterlies are dry, cold prevailing winds that blow high pressures in areas like in the North and South Pole.

Jet Streams

Jet Streams are fast flowing winds,relatively narrow air currents found in the atmosphere. They are around 10 kilometers above the surface of the earth.
