Why is it that when there is a low pressure area there is warmer air?

Warmer air is less dense because the molecules have greater relative motion. Warm air rises over cooler, denser air.

What is it called when the movement of air molecules from an area of air pressure to an area of low air pressure?
Wind.
How is wind creating?
It is affected by changes in pressure and temperature. When one area heats up more than another area that it is next to, the difference in pressure creates wind. It is a rotation cycle of cool air and warm air. Air that grows warmer rises upward.
Where does low pressured air move to?
Usually a low pressure area is where all the air moves to. A high pressure area is the one that will move- to try to balance the pressure differential.
What is a low-pressure system and what is a high-pressure system?
The difference is that Low air pressure has less air molecules pushing down in one area and high air pressure has more air molecules pushing down in one area.
Does the Intertropical Convergence Zone have high pressure with rising air?
Low pressure is associated with rising air. The ITCZ is an area of low pressure.
Why is cool air an area of low pressure?
Cool air is an area of low pressure because temperature is directly proportional to pressure. So when the pressure is low, the air is cool (low temperature).
What is it called when the movement of air molecules from an area of air pressure to an area of low air pressure?
Wind.
What moves from a high pressure area to a low pressure area?
Air.

What do you mean by low pressure area and high pressure area?
Our atmosphere is divided into layers of air which exerts pressure on the ground, at the earth. The higher the distance from the ground, lower the pressure of the air exerted by it. (i.e why astronauts float above the atmosphere with no pressure or gravitation pull). Atmosphere gets heated up by the sun and so the ground. This causes the moisture to evaporate and the air above the ground becomes warmer and both rise up. Warmer air are less dense, lighter in weight and have a tendency to hold more water. This warmer air rises up above the cold air (which is heavier or highly denser). The areas which witness such type of phenomenon are called as low pressure areas. At a later stage, the warmer or low pressure air, above the cold high pressure air, gets cooled, condensed and causes precipitations. Low pressure air is usually marked with cloudy and windy sky. Hence we say that Low pressure areas gets torrential rainfall. Whereas in high pressure areas, one would witness dry and clear sky (due to lack of condensed air or clouds)
Do clouds rise in the center of a low pressure or high pressure area?
Air rises in a low pressure area and sinks in a high pressure area.
What is the movement of air from an area of low air pressure to high air pressure?
density
Which is warmer the high pressure system or the low pressure system?
The high pressure system is warmer then the low pressure system . simple reason pressure is high when the molecules of gas are vibrating more violently then they do in normal routine ( vibrations of molecules can only be increased by increased temperature) hence if the pressure is high the temp will always be warmer then in low pressure area .
How are the air masses and fronts different?
Air mass - refers to any area of high or low pressure. A front - is the point at which an area of high pressure meets an area of low pressure.
What will move from a high pressure to a low pressure area?
Air.
How are the terms front and air mass different?
Air mass - refers to any area of high or low pressure. A front - is the point at which an area of high pressure meets an area of low pressure.
When an area of low pressure air is surrounded by high pressure air what is it called?
it is a tornado
