Write A Short Note on Wind//CBSE ,ICSE AND ISC GEOGRAPHY

The wind is a moving air that is caused due to the differences in air pressure within our atmosphere.

A wind is named after the direction from which it blows, e.g. the wind blowing from the west is called westerly.

 

There are different types of winds which can be broadly divided into:

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” 

Seasonal winds :These winds change their direction in different seasons.

The main cause of periodic winds is the unequal heating and cooling of the Earth’s surface.

These winds change their direction periodically with the change in the seasons.

For example monsoons in India.

Local winds :These blow only during a particular period of the day or year in a small area.

 Local winds are unique to certain well-defined areas.

They affect the local weather conditions of that place only.

In different parts of the world, these winds are known by different names

For example, Loo, Harmattan, Foehn, and Chinook.
