Effect of convection on wind formation
Effect of convection on wind formation
Convection plays the main role in the formation of winds in the atmosphere.
On the banks of reservoirs on a hot summer day, the water is heated by the sun no longer than dry land.
Accordingly, the air above land heats up more than above water.
Its density decreases, and pressure also decreases.
It is less over land than over water, so cold air moves from the reservoir to land, that is, the wind blows.
At night, on the contrary, land cools faster than water, and over land the air is colder than over a body of water.
The wind blows from land to body of water.
These winds are called day and night breezes respectively.
