The Sea breeze occurs at day and land breeze occurs at night because the specific heat capacity of land is less in comparison to the sea that is water. At day, the land is heated faster than the water and the air above the land becomes hot and moves upward . To full fill this gap the air above the sea blows towards the land and sea breeze occurs .
Similarly, at night, the land cools faster while the sea cols slower. Now the air above sea water becomes less dense and the air above the land is denser. Thus air from land blows towards the sea and land breeze occurs .
[caption id="attachment_14057" align="aligncenter" width="274"] land and sea breeze[/caption]Sea breeze tends to decrease the air temperature. Land breezes usually blow dry winds. While the sea breeze contains more amount of moisture due to the particles absorbed from the water bodies. Hence, both the land breeze and sea breeze occur near water bodies.Land breeze, a local wind system characterized by a flow from land to water late at night. Land breezes alternate with sea breezes along coastlines adjacent to large bodies of water. ... Since the surface flow of the land breeze terminates over water, a region of low-level air convergence is produced.a breeze: Sea breeze blows during the day and the land heats up faster than the sea.
The land breeze develops at night when the temperature pattern between the ocean and land are reversed. In a land breeze the land will be cooler than the ocean. ... A land breeze will often be weaker than a sea breeze since the temperature difference between the land and water is not as great.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.
By contrast, a land breeze or offshore breeze is the reverse effect: dry land also cools more quickly than water and, after sunset, a sea breeze dissipates and the wind instead flows from the land towards the sea. Sea breezes and land breezes are both important factors in coastal regions' prevailing winds.
