Hint: It is one of the factors which affects the temperature or climate of any place.
It is mainly affected by the rotation of Earth. They occur differently in different places or regions.

Complete answer:
Wind is defined as the movement of air from a high pressure area to any low pressure area which is affected by the rotation of the Earth. This rotation is also known as the Coriolis force which is explained by Ferrel's Law. Regarding its categorization, there are mainly five types of winds:-
Planetary winds – They are defined as those winds which are distributed in the lower portion of the atmosphere and blow regularly throughout the year in limited areas of latitudinal belts in the north-east and south-east direction or from high pressure to low pressure regions.
Trade winds – They are also known as Tropical Easterlies which blow from the right in the Northern Hemisphere to the left in the Southern Hemisphere because of the Coriolis Effect and the Ferrel’s Law.
The Westerlies – They are also known as Shrieking Sixties, Furious Fifties and Roaring Forties blowing from the subtropical high pressure belts to sub polar low pressure belts.
Periodic Winds – It is defined as those winds which change the direction periodically according to change in the season.
Local Winds – They are defined as those winds which are created due to the pressure difference between the air over the land and sea regions.

Note:Winds are measured with the help of anemometers and wind vanes.
Winds are caused because of the uneven heating between the land and sea or uneven heating between the equator and pole.
Periodic Winds are further classified into four types, i.e. Monsoon winds, Land breeze, Sea breeze and mountain and valley breeze.
