WindWind
Land Breeze – at night the land cools faster than the water, therefore Land Breeze – at night the land cools faster than the water, therefore the air above it cools and descends, the air over the sea rises, surface the air above it cools and descends, the air over the sea rises, surface air moves to sea, higher air moves inlandair moves to sea, higher air moves inland
Sea Breeze – during the day, more common on hot sunny days, the Sea Breeze – during the day, more common on hot sunny days, the land heats, causes the air over the land to rise, the air above the water land heats, causes the air over the land to rise, the air above the water is cooler and moves in over land and creates a circular patternis cooler and moves in over land and creates a circular pattern
