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.
What are the six types of winds?
Ans. The different types of winds on earth are planetary winds, trade winds, periodic winds, local winds, and westerlies . 2.
What is the most prevailing wind?
The westerlies or the prevailing westerlies are the prevailing winds in the middle latitudes (i.e. between 35 and 65 degrees latitude), which blow in areas poleward of the high pressure area known as the subtropical ridge in the horse latitudes.
What are easterly and westerly winds?
Easterly winds blow from the east, while westerly winds blow from the west .
What are the types of prevailing winds?
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 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 are the 2 types of prevailing winds?
- Tropical Easterlies: From 0-30 degrees latitude (Trade Winds).
- Prevailing Westerlies: From 30-60 degrees latitude (Westerlies).
- Polar Easterlies: From 60-90 degrees latitude.
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 causes the prevailing winds?
Winds occur where high-pressure air masses seek low-pressure areas . Prevailing winds are largely predictable and named for broad areas of the Earth over which they form. Convection cells circulate air flow and help regulate temperature around the globe.
What is my prevailing wind direction?
Prevailing winds are the direction that the wind blows most often in a location . ... In the tropical or lower latitudes winds move east to west and are called the Easterlies. In the mid-latitudes of North America, Europe and Asia, winds move west to east, naming them the Westerlies.
What are primary winds?
Primary winds are nothing but the Permanent winds . Permanent winds are also called Global winds or Planetary winds. These are again classified into 3 different types of winds namely, Trade winds, Westerlies and Polar Easterlies.
What is wind caused by?
Wind is the movement of air, caused by the uneven heating of the Earth by the sun and the Earth’s own rotation . Winds range from light breezes to natural hazards such as hurricanes and tornadoes.
Which best describes why wind movement is predictable?
Q. Which best describes why wind movement is predictable? Air moves from areas of low altitude to areas of high altitude. Air moves from areas of high pressure to low pressure.
Why is wind important to humans?
Wind is a renewable energy source . Overall, using wind to produce energy has fewer effects on the environment than many other energy sources. ... Wind turbines may also reduce the amount of electricity generation from fossil fuels, which results in lower total air pollution and carbon dioxide emissions.
