- A sea breeze or onshore breeze is any wind that blows from a large body of water toward or onto a landmass; it develops due to differences in air pressure created by the differing heat capacities of water and dry land. As such, sea breezes are more localised than prevailing winds.
The second figure is a Land Breeze
- A land breeze is a local nighttime and early morning wind that occurs along coasts and blows offshore (from the land out to sea). It arises at sunset when the sea surface is warmer than the adjacent land due to the land having a lower heat capacity and cooling off faster.
Explanation:
Land and sea breezes develop because of differential heating and cooling of adjacent land and water surfaces. Water has a greater heat capacity than land, i.e. land absorbs and emits radiation more efficiently and faster. The diurnal temperature differentials between land and water create a distinctive wind pattern — an example of thermal circulation.
During the day the air over land is heated and expands more rapidly than that over water, resulting in pressure changes and a thermally driven circulation with rising air over land and sinking air over water. At the shoreline the cool sea air blows inland and is known as a sea breeze.
