During the day, under the irradiation of the sun, the land heats up rapidly, the temperature is higher than that of the ocean, and the hot air expands and rises, forming a pressure difference between the land and the ocean. The air flows from high pressure to low pressure, that is, the wind blows from the sea surface to the land, thus forming a sea breeze.
At night, the sea temperature rises, the sea surface gas expands and rises due to heating, and the air on the land drops at night, which also forms a pressure difference and forms a land wind, which blows from the land to the sea. The land wind is the local night and early morning wind, which blows along the coast to the offshore. It appears at sunset. Because of the low heat capacity of the land, the cooling rate is faster, and the sea surface is warmer than the adjacent land.
Then it continued until the early hours of the morning, until the heating of the day began. Land breeze is the opposite of sea breeze. Sea breeze is a gentle wind that blows from the ocean to the land to keep you cool on the hot beach. Although it is usually associated with the ocean coastline, land winds can also be felt near lakes and other large water bodies.
Like all winds, land breeze is formed by the difference of temperature and air pressure. Land breeze comes from the ability of different surfaces to keep heat. During the day, the sun heats the earth's surface, but only a few inches deep. When night falls, the ground temperature drops rapidly, because the ground is no longer irradiated by the sun, and the heat quickly radiates back to the surrounding air.
The influence of landwind:
1, Climate Impact: Land breeze and sea breeze are one of the important factors that affect the climate of a region. Land breeze can bring dry and hot air, making the local weather very hot, while sea breeze can bring wet and cold air, making the local weather humid.
2. Energy utilization: Land breeze and sea breeze are also a form of renewable energy, and wind power can be used to meet energy demand.
3. Environmental impact: Land breeze and sea breeze will also have an impact on the environment. For example, in coastal areas, land breeze and sea breeze will bring many pollutants, such as particulate matter and sulfur dioxide, which will affect air quality.
