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

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 due to low pressure. Clouds do not precipitate in deserts due to low pressure.
Which direction does air flow in high pressure?
High pressure air travels "downwards and clockwise"
Does wind occurs as air moves from a place of low air pressure to a place of high air pressure?
Winds occur as air moves from high pressure to low pressure.Wind occurs as air moves from a place of low air pressure to a place of high air pressure is a true statement.
What type of pressure does cold air have?
high pressure because the air is very dense. so it's pressure is also very high
What is a high pressure center of dry air called?
A high pressure center of dry air is called an anticyclone
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 due to low pressure. Clouds do not precipitate in deserts due to low pressure.
What does high air pressure?
air pressure is the amount of air pushing down on you and high pressure is air that rises.
Why air pressure is high at low places?
because air pressure is high
The deserts of the Sahara and Australia are associated with .?
subtropical high pressure centers
What are the deserts of the Sahara and Australia are associated with?
Subtropical high pressure centers
What are the deserts of the Sahara and the Australia associated with?
Subtropical high pressure centers
The deserts of the Sahara and the Australia are associated with what?
Subtropical high pressure centers
What is injected into high pressure air in a jet?
Answer this question… What is injected into high pressure air
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.
Why air move from low to high air pressure?
In areas of high pressure the air is being squeezed more by the air above it than it is in areas of lower pressure. So the air will tend to get pushed away from the high pressure area.
