Deserts have a high air pressure so the air sinks, making the no. of clouds less and bringing expected dry weather.

High pressure areas form when an airmass cools over a cool land or ocean surface. The cooling causes the air layer to shrink, becoming slightly thinner. This shrinkage then causes surrounding air in the upper troposphere to fill up the extra space. The added weight of the extra air causes higher pressure at the surface.

Remember: cool air------> more dense

Do high pressure belts give rise to many of the world's largest deserts?

Yes, high pressure belts, especially around 30 degrees north and 30 degrees south contribute to the formation of deserts. High pressure is sinking air that inhibits air from rising to carry moisture into the higher atmosphere and suppresses the development of rain storms.


What are Mid latitude deserts are caused primarily by?

The descent of dry air at these latitudes.


Clouds do not precipitate in deserts due to Low Humidity or Low Pressure or High Wind velocity or High temperature?

Clouds do not precipitate in deserts primarily due to low humidity. Deserts have very dry air with low moisture content, which limits the formation of rain clouds. The low humidity prevents sufficient condensation of water vapor in the atmosphere to form clouds that can produce precipitation.


Why do deserts not receive rain?

Deserts do not receive much rain because they are located in regions where the air is dry and stable, preventing the formation of clouds and precipitation. Additionally, deserts are often situated in areas where high-pressure systems dominate, inhibiting the movement of moist air and causing minimal rainfall.


What does high air pressure?

air pressure is the amount of air pushing down on you and high pressure is air that rises.


Which global pressure system is responsible for deserts such as the Sahara and Kalahari in Africa?

The deserts such as the Sahara and Kalahari in Africa are primarily influenced by the subtropical high-pressure systems, specifically the Hadley cell circulation. These systems create descending air that warms and dries, inhibiting cloud formation and precipitation. As a result, areas within these high-pressure zones experience arid conditions, leading to the development of deserts. Additionally, the location of these deserts within the tropics further contributes to their dry climates.

How does atmospheric pressure create deserts?

High atmospheric pressure generally suppresses the development of rain clouds. The earth has belts of high pressure, usually between latitudes of 25 - 35 degrees north or south, where many of the earth's deserts are located.
