Winds and Breezes


Global Winds

Global winds blow across the continents-winds follow curved patterns due to the Coriolis Effect. The Coriolis effect causes winds travelling north to curve to the east and winds travelling south to curve to the west. Polar easterlies ,westerlies and trade winds are all types of global winds. Also global winds always blow in the same direction.

Local Winds

Local winds only occur in a small area due to local heat patterns. Some examples of local winds are sea, city, valley, and land breezes. Local winds will occur anywhere there is unequal heating.

Sea Breeze

On a hot summer day at the beach, the land heats up faster than the water. The warmer air over land rises, while the cooler air over the ocean rushes in to take its place. This wind is called a sea, or onshore, 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 is called a land breeze or offshore breeze. A breeze that blows from the land to the sea and occurs at night because the land cools faster than water.



Sea and Land Breezes are the winds that blows onto the shore from sea to land during the day and blows off the shore in the evening. During the summer, the sea breezes are stronger then they are in winter because of the big temperature changes between land and ocean that is caused by the hot climate.At night, the roles switch. The air over the ocean is now warmer than the air over the land. The land loses heat quickly after the sun goes down and the air above it cools too. This can be compared to a road. During the day, the road heats up and becomes very hot to walk on. At night, however, the road is cool to the touch. The ocean is able to hold onto this heat after the sun sets and not lose it as easily as the land next to it does.
