What Are Local Winds?

Local winds are one of a number of winds influenced predominantly by the topographic features of a relatively small region.  There are 2 types of local winds: land breeze and and sea breeze.  A land breeze is a breeze moving from land out to the sea.  A sea breeze is a breeze moving from sea to land.

What Are the Causes of Local Winds?

Local winds are caused by the unequal heating of Earth's surface within a small area.At night, the land cools faster than the sea due to specific heat, so the air above the land sinks and moves toward the ocean, causing a land breeze.During the day, air rising from the land draws in cooler air from the ocean, causing a sea breeze.

What Are the Effects of Local Winds?

Land Winds:Air temperatures decrease at night.A low pressure zone forms above the land surface.A high pressure zone forms as the cooler land cools the air immediately above the surface.Winds at the surface flow from high to low pressure.Sea Breeze:Air temperatures decrease in the day.A high pressure zone forms above the land surface.Winds at the surface flow from low to high pressure.

What Locations Are Affetected by Local Winds?

Locations affetected by local winds are areas near the ocean.
