What phenomenon describes the movement of air from land to sea at night?

The phenomenon that describes the movement of air from land to sea at night is known as land breeze. During the day, the sun heats the land more quickly than it heats the water. As a result, warm air rises over the land, creating an area of lower pressure that draws in cooler air from over the sea, which is known as a sea breeze.

At night, the situation reverses. The land cools down rapidly while the water retains heat more effectively. This results in the air over the land becoming cooler and denser compared to the air over the water. The cooler, denser air over the land moves towards the less dense, warmer air over the sea, creating a land breeze. This process typically occurs during clear nights, where the temperature difference between land and water is more pronounced. Thus, a land breeze is characterized by a movement of air from the land to the sea after sunset.
