Question

In the coastal area, the wind current moves from the sea towards the land during the day; but during the night it moves from land to the sea. Discuss the reason.

Answer 1

1. Wind flow due to pressure difference in areas.
2. During the daytime because of heat absorbed by the land, a low-pressure area is created.
3. Due to the evaporation process taking place in the ocean, the ocean is cooler than the land and a high-pressure area is created.
4. So during the daytime, wind flow from high pressure to the low-pressure area that is from sea to land.
5. At night the land is cooler than the sea so, wind flow from land to sea.
