This causes a small temperature gradient between the ocean surface and the nearby land at night and the wind will blow from the land to the ocean creating the land breeze. Sea breeze, a local wind system characterized by a flow from sea to land during the day.
Sea breezes alternate with land breezes along the coastal regions of oceans or large lakes in the absence of a strong large-scale wind system during periods of strong daytime heating or nighttime cooling. The wind speed tends to decrease after sunset because at night the surface of the Earth cools much more rapidly than does the air above the surface.
If there is a low pressure area or storm in the region the winds will blow day or night. In the morning, when sunlight returns and begins to warm the surface layer, the wind from above gradually builds downward and returns to the surface. This breeze occurs because of the land - sea temperature gradient, normally in the night time.
During the night, the land drops heat suddenly in the form of longwave radiation and the air above land cools too. Also Know, what is called land breeze?
The breeze that blows from the land toward the sea after sunset. The land cools more quickly than the ocean, cooling the air above it. The warmer air above the water continues to rise, and cooler air from over the land replaces it, creating a breeze. Compare sea breeze. During the day, the land surface heats up faster than the water surface. Therefore, the air above the land is warmer than the air above the ocean. The bottom of the following image illustrates the land breeze that occurs at night.
Recall that the land surface cools quicker than the water surface at night. This means the air over the water is warmer, less dense and begins to rise. Low pressure is created over the water. Cold and dense air over the land begins to move to the water surface to replace the warmer rising air.
The cool breeze from the land is called a land breeze. The air over the ocean is now warmer than the air over the land. The land loses heat quickly after the sun goes down and the air above it cools too. This causes a small temperature gradient between the ocean surface and the nearby land at night and the wind will blow from the land to the ocean creating the land breeze. What is the effect of land breeze? 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. What is land breeze and sea breeze with diagram? Land breeze: Land breeze blows during the night from land to sea and the land becomes cooler faster than the sea. The air above the sea becomes less dense i.
The cooler air from the land moves in to take its place. During the day, the sun heats land surfaces, but only to a depth of a few inches. When night comes around, the temperature of the land drops quickly because the surface no longer receives insolation from the sun, and heat is rapidly re-radiated back to the surrounding air. Meanwhile, water retains more of its heat than land surfaces because of its higher heat capacity. The water along the shore becomes warmer than the coastal land, creating a net movement of air from the land surfaces toward the ocean.
The movement of the wind is a result of differences in air pressure over the land and the ocean warm air is less dense and rises, while cool air is denser and sinks.
As the temperature of the land surfaces cools, the warm air rises and creates a small area of high pressure near the land surface. Since winds blow from areas of high pressure to areas of low pressure, the net movement of air wind is from the shore to the sea. Here's a step-by-step explanation of how land breezes are created:. As the summer wears on, the temperature of the sea slowly rises in comparison to the daily temperature fluctuations of the land.
As a result, land breezes last longer. If there is sufficient moisture and instability in the atmosphere, land breezes can lead to overnight showers and thunderstorms just offshore. So while you might be tempted to take a nighttime beach walk, be sure to follow lightning safety guidelines to reduce your risk of a lightning strike.
