There are three prevailing wind belts associated with these cells: the trade winds, the prevailing westerlies, and the polar easterlies (Fig.
What are the 3 main global winds and where are they found?
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.
What are the types of wind patterns?
The four major wind systems are the Polar and Tropical Easterlies, the Prevailing Westerlies and the Intertropical Convergence Zone . These are also wind belts. There are three other types of wind belts, also. They are called Trade Winds, Doldrums, and Horse Latitudes.
What are the 4 types of winds?
Ans. The different types of winds on earth are planetary winds, trade winds, periodic winds, local winds, and westerlies . 2.
What are the 3 major wind belts?
“Between the poles and the equator, each hemisphere has three major surface wind belts: the polar easterlies , which extend from the poles to about 60 degrees latitude; the prevailing westerlies, which stretch from about 60 degrees to 35 degrees; and the trade winds, which pick up at about 30 degrees, and blow towards ...
What wind belt do we live in?
Note that the U.S. lies primarily in the Westerly Wind Belt with prevailing winds from the west.
What are the major wind patterns on Earth?
The Earth contains five major wind zones: polar easterlies, westerlies, horse latitudes, trade winds, and the doldrums . Polar easterlies are dry, cold prevailing winds that blow from the east. They emanate from the polar highs, areas of high pressure around the North and South Poles.
Is wind a type of advection?
Advection is a lateral or horizontal transfer of mass, heat, or other property. ... In contrast, convection, the vertical movement of mass or transfer of heat, manifests itself as air currents. Accordingly, winds are a result of advection , while air currents are a result of convection.
What are the 7 winds?
| Beaufort number Description Wind speed | 6 Strong breeze 10.8–13.8 m/s | 7 High wind, moderate gale, near gale 28–33 knots | 32–38 mph | 50–61 km/h |

What are the two main types of winds?
Primary Wind or Planetary Wind
Primary winds constantly blow throughout the year in a particular direction. Primary winds are also known as prevailing winds or planetary winds. Trade winds, westerlies and easterlies are different types of primary wind.
How are winds classified?
Winds are commonly classified by their spatial scale, their speed and direction, the forces that cause them, the regions in which they occur, and their effect . ... Long-duration winds have various names associated with their average strength, such as breeze, gale, storm, and hurricane.
What wind belt is Hawaii in?
The regular winds in the Northern Hemisphere, such as those in the Hawaiian Islands, blow from the Northeast , and in the Southern Hemisphere the regular winds blow from the Southeast.
What is the driving force of the six wind belts on the earth?
The tilt of the earth creates seasons. It creates the wind belt patterns known as the Coriolis Affect. Wind ...... . The differences in these heating patterns cause convection currents.
What causes wind belts?
Wind belts are formed due to unequal heating of the earth and the earth’s rotation . ... And don’t forget our rules regarding the Coriolis effect: winds are deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere, and this is as they blow from high to low pressure.
How is wind helpful to Earth?
Wind is the fastest growing source of electricity around the world . Generating power from the wind leaves no dangerous waste products behind and best of all its supply is unlimited. ...
What is the name of the winds between 60 and 90 degrees latitude?
Polar Easterlies : From 60-90 degrees latitude.
