In daytime, the land heats, and the air rises causing the air to move toward shore. What is this phenomenon called?

Daytime coastal airflow driven by the land-sea temperature difference. When the sun heats the land more quickly than the sea, the air over land rises and creates lower pressure near the surface. Cool air from the sea moves toward the shore to replace that rising air, producing a flow from sea to land along the coast—the sea breeze. This breeze tends to strengthen in the afternoon as heating peaks. Other winds listed occur in different contexts: a monsoon involves seasonal wind reversals with heavy rains, trade winds are steady easterlies near the equator, and a Chinook is a warm, dry wind that descends the leeward side of mountains.
