What is the reason for the formation of land-sea breeze?

1, the atmospheric motion form formed by the difference of thermal properties between land and sea. During the day, under the irradiation of the sun, the land heats up quickly, the temperature is high, the air expands and rises, and the air pressure near the ground decreases. Therefore, near the ground, the air pressure of the ocean is higher than that of the land, and the wind blows from the ocean to the land, forming a "sea breeze"; At night, the situation is just the opposite, and the air movement forms a "land wind".

2. The sea-land breeze can only be seen in calm weather. If there is a strong weather system, such as squall line and storm, you can't see the phenomenon of land-sea wind. In addition, if it is cloudy, the time when the land breeze blows will often be delayed for a long time, and the time when the sea breeze appears will also be delayed, sometimes even starting around 12.

3. The sea breeze brings water vapor, which increases the humidity on the land, lowers the temperature obviously, and even forms low clouds and fog. Coastal areas are cooler than inland in summer and milder than inland in winter, which is related to sea breeze. So the sea breeze can adjust the climate in coastal areas.
