A land breeze is a local wind that blows from the land over onto a lake or ocean. Land breezes occur at night as the land cools off very rapidly, creating sinking air and high pressure, whereas the water will be releasing the energy stored from the daylight, creating rising air and low pressure. A sea breeze is a local wind that blows from an ocean. A lake breeze is a local wind that blows from a lake. Sea breezes occur during the day due to the land heating up much faster than the water (water has a high specific heat) and creating rising air a low pressure. During the day, the sun heats the mountain slopes faster than the air in the valley. Uneven heating causes lower pressure near mountain tops, creating a valley breeze as air travels upslope Mountain breezes occur at night. At night, the air along the mountain slopes cools more quickly, and sinks down to the valley.
