Convection: Land Breeze, Sea Breeze

Land Breeze













In the night, the temperature of the ocean is warmer than the land. The warm air then rises to form clouds. The cool air above the land will sink and rushes towards to ocean the fill the space there, thus we get our land breeze.













In the day, it is the exact opposite of the night. Instead of the ocean being warmer than the land, the air above the land is now warmer than the air above the ocean as the sun is out and the ocean is a poorer conductor of heat. The warm air above the land rises up to form clouds while the cool air above the ocean sinks. The cool air then rush towards the land, thus we get our sea breeze.
