Due to horizontal differences in air pressure, air flows from areas of high pressure to areas of low pressure. Horizontal movement of the air is called wind. The three types of winds are given below :
Planetary Winds : The winds blowing throughout the year from one latitude to another in response to latitudinal differences in air pressure are called planetary or prevailing winds. Trade winds, Westerlies and Polar winds are planetary winds.
Periodic Winds : Periodic winds change their direction periodically with the change in season, e.g. Monsoons, Land and Sea Breeze etc.
Local Wind : Local winds develop as a result of local differences in temperature and pressure. Loo is an example of local winds.
Hurricane : This is also known as tropical cyclone or tropical storm. This is a disturbance of about 650 km across, spinning around a central area of very low pressure, with winds over 140 km per hour.
