People who live on the coast of C, the wind direction they often feel on a clear day is

sea breeze!

The formation of sea-land wind is caused by the thermal circulation caused by the difference in thermal properties of sea and land.

During the day, the surface of the earth heats up due to solar radiation. Since the heat capacity of land soil is much smaller than that of sea water, land heats up much faster than the ocean. Therefore, the temperature on land is higher than that on the nearby ocean. The air on the land rises due to thermal expansion, and the ocean temperature is low. Under the action of the horizontal pressure gradient force, the air above flows from the land to the ocean, sinking to the surface of the sea, and high air pressure is formed on the sea surface. Under the action of the horizontal pressure gradient force, the air Sea breeze flows from the ocean to the land;

After sunset, the land cools down faster than the ocean; at night, the sea temperature is higher than the land, and a thermodynamic circulation opposite to that during the day occurs, that is, high pressure is formed on the land and low pressure is formed in the ocean. , the near-surface air flows from land to ocean under the action of horizontal pressure gradient force, forming land breeze.
