Answer:
Wind is the movement of air from high pressure area to low pressure areas. There are different types of winds. They can basically be divided into:
Permanent or Planetary winds.
Periodic winds
Local winds.
Permanent Winds:
The trade winds, westerlies and easterlies are the permanent winds. These blow constantly throughout the year in a particular direction. They are also known as prevailing winds or planetary winds. They are of three types-trade winds, westerlies and polar winds.
Periodic Winds:
Periodic winds, or seasonal winds, are those that blow without fail at a certain time of the year or day. But they do not blow permanently like the planetary winds. Seasonal winds change their direction suddenly or deflect from their original path because of seasonal variations in temperature or pressure. Periodic winds are mainly caused by unequal heating and cooling of the Earth’s surface, and due to surface variations in atmospheric pressure. The monsoon winds and land and sea breezes are example of periodic winds.
Local Winds:
Local winds are unique to certain well-defined areas. They blow over a small area from a small area from a particular period. They affect only the local weather conditions of that place. They are known by different names in different parts of the world. For example: Loo, Harmattan, Foehn, Chinook
