global and local winds

by:Allie Hearn

Global winds

Blow across continents winds due to the Coriolis effect. The Coriolis effect causes winds traveling north to curve to the east and winds traveling to the west. Polar easterlies, westerlies, and trade winds are all types of global winds. Global winds blow in the same direction every day. Global winds are really large air masses that are created mainly as a result of the earth’s rotation, the shape of the earth and the sun’s heating power.

Local winds

Local winds -only in a small area due to local heat patterns on a small scale. Some examples of local winds are sea breeze, land breeze, and mountain and valley breeze. Unequal heating Cause's local winds.

land breeze

Land breeze-After sunset, the land cools down faster than the water. The warmer air over the ocean rises, while the cooler air over land rushes in to take its place. This wind is called a land, or offshore, breeze. A breeze that blows land to sea.

Sea breeze

Sea breeze-on a hot summer day at the beach, the land heats up faster than water. The warmer land over land rises, while the cooler air over the ocean rushes into take its place. This wind is called sea, or onshore, breeze. Also a breeze that blows from sea to land.
