Question

Explain why is there a change in the wind direction in coastal areas during the day and at night.

Answer 1

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 causes a small temperature gradient between the ocean surface and the nearby land at night and the wind will blow from the land to the ocean creating the land breeze

Answer 2

due to atmospheric pressure which is high during day due to evaporation of of water and low during night due to condensation of water.
