Question

the appearance of areas of low and the high pressure in coastal areas at night​

Answer 1

Answer:

Since air travels from a region of higher pressure to an area of lower pressure and at night the land cools off faster than the sea owing in differences in their heat capacity, air will flow from land to ocean. During night the temperature of land is low and therefore the air will be at higher pressure.

Answer 2

Answer:

Dear Student

• At night, both land and sea starts to cool. The land surface cools down much faster as compared to the water surface. Therefore, the air over land is cooler in comparison to the air over water. A high pressure area is thus created over the land surface and a low pressure area prevails over the water surface.

• Since air travels from a region of higher pressure to an area of lower pressure and at night the land cools off faster than the sea owing in differences in their heat capacity, air will flow from land to ocean. During the night the temperature of the land is low and therefore the air will be at higher pressure.

• Since air travels from a region of higher pressure to an area of lower pressure and at night the land cools off faster than the sea owing in differences in their high temperature capacity, air will pass from land to ocean.

Explanation:

• During the time of night, the temperature of land will short and therefore the air will be at more pressure.

• At night, the roles will become reverse.

• The wind of the ocean is now moderately hot than the air up the land.

Why there is change in the wind direction in coastal areas during the day and at night?

• during the day, the land gets heated more rapidly than the water around. Hence, the air above the land will be heated and starts rising, hence a low pressure area is formed over land.as air flows from a high pressure region to a low pressure region, the wind starts blowing from sea to land.

• during the night, since the water cools down slower than the land the air above water will be warmer than the air above land. So there takes place a complete reversal in the direction of winds in coastal areas.

• this is due to the concept of Land breeze and Sea breeze.

• during the day, the land gets heated up fast and rise up. which creates a low pressure in the land so the cool air above the sea, goes and occupies a space in the land.

• so during the day, the wind blows from sea to land in coastal areas.

• during the night, the reverse process takes place.

• and the wind blows from land to sea at night time.
