Asked by: Christina Burton
There are three prevailing wind belts associated with these cells: the trade winds, the prevailing westerlies, and the polar easterlies (Fig. 3.10).
What are the 3 main global winds and where are they found?
There are three pairs of major global wind systems, or wind belts: trade winds, westerlies, and polar easterlies. Trade winds are wind belts that blow from 30° lati- tude almost to the equator. They curve to the west as they blow toward the equator. Westerlies are wind belts that are found between 30° and 60° latitude.
What are the 3 winds?
There are three main types of planetary winds – the trade winds, the westerlies and the easterlies.
What are the 3 global wind belts and what degree of latitude can you find them?
Polar Easterlies: From 60-90 degrees latitude. Prevailing Westerlies: From 30-60 degrees latitude (aka Westerlies). Tropical Easterlies: From 0-30 degrees latitude (aka Trade Winds).
How many global wind belts are there?
Three
Summary. Global winds blow from high to low pressure at the base of the atmospheric circulation cells. The globe has six atmospheric circulation cells. Three are north of the equator and three are south.
What is a wind belt?
: a belt or row of trees planted to serve as a windbreak : shelterbelt.
What are the major trade winds?
Because winds are named for the direction from which the wind is blowing, these winds are called the northeasterly trade winds in the Northern Hemisphere and the southeasterly trade winds in the Southern Hemisphere. The trade winds of both hemispheres meet at the Doldrums.
What are the global wind belts their boundaries?
The global wind belts are the three wind belts or wind patterns that cover the planet: the tropical easterlies (or the trade winds) are found near the equator, the polar easterlies are found at the north and south poles, and the prevailing westerlies are found between the two.

Why are there three different wind patterns in each hemisphere?
The unequal heating of the surface of the planet, i.e., the temperature differences between the Equator and the Poles, combined with the Earth’s rotation, is responsible for the creation and development of six major air circulation patterns, three in each hemisphere.
What are the 3 types of atmospheric circulation cells called?
The global circulation
In each hemisphere there are three cells (Hadley cell, Ferrel cell and Polar cell) in which air circulates through the entire depth of the troposphere. The troposphere is the name given to the vertical extent of the atmosphere from the surface, right up to between 10 and 15 km high.
What are global wind patterns?
Global Wind Patterns. Wind is mainly the outcome of a thermodynamic principle and the Coriolis effect due to the counterclockwise rotation of the earth. Warm air around the equator is lifted, which creates a suction effect for air masses coming from higher (or lower) latitudes.
What are polar easterlies and westerlies and Tradewinds?
Polar easterlies flow to low-pressure areas in sub-polar regions. Trade winds: They are the powerful prevailing winds that blow from the east across the tropics. Trade winds are also known as tropical easterlies. They start blowing from the sub-tropical high-pressure areas towards the equatorial low-pressure belt.
What is south westerlies and north westerlies?
Westerlies blow in the middle latitudes between 30 and 60 degrees latitude, and originate from the high pressure area in the horse latitudes towards the poles. Under the effect of the Coriolis force, they become the south westerlies in the northern hemisphere and Northern westerlies in the southern hemisphere.
What are westerlies known as?
The westerlies, anti-trades, or prevailing westerlies, are prevailing winds from the west toward the east in the middle latitudes between 30 and 60 degrees latitude. They originate from the high-pressure areas in the horse latitudes and trend towards the poles and steer extratropical cyclones in this general manner.
