Wind

local and global

local winds

local winds are small scale winds, that are caused by a temperature difference. Examples of local winds are sea breezes and land breezes, and mountain and valley breezes.Terrain can have a strong influence on local winds, and the more varied the terrain, the greater the influence.

Global winds

Global winds are large air masses that are created as a result of the earth's rotation, the shape of the earth and the sun's heating power. Examples global winds are three wind belts: Polar Easterlies: From 60-90 degrees latitude. Prevailing Westerlies: From 30-60 degrees latitude (Westerlies).

land and Sea breezes Compare and Contrast

Sea Breezes

A sea breeze is a gentle wind that develops over bodies of water near land due to differences in air pressure. It is common along coasts during the morning as solar radiation heats the land more quickly than the water.

Land Breezes

Land Breezes are breezes blowing toward the sea from the land, especially at night, due to the relative warmth of the sea.
