Air pressure occurs by gravity. Gravity sucks everything down from the atmosphere, including the air. Becasuse the air is being pulled down fast, it creates pressure from the speed of the pulling.

∙ 11y agoAtmospheric air pressure is the relative weight of air (and moisture) compressing a surface due to gravitational pull and temperature. Or air pressure can be mechanically increased or decreased within a specific container by compressing it or decompressing it or heating or cooling it.
an increase in temperature of an unchanged volume of air will increase the pressure. A decrease will decrease the pressure.
A decrease in volume of air at an unchanged temperature will increase the pressure. An increase will decrease the pressure.
Atmospherically, an increase in altitude results in decreased air pressure. An increase in relative humidity (moisture) increases air pressure and an increase in air temperature decreases the atmospheric air pressure.
*The atmospheric air pressure on Earth at sea level at 32 degrees fahrenheit (low relative humidity) is 14.696 pounds per square inch (30 inches of Mercury at 60 F), or 1 atmosphere.
A bar is 14.35 psia, determined to be the air pressure at 1000 feet altitude at 32 degrees Fahrenheit. (that's the altitude at which the samples were taken)
An atmosphere is equal to 1.013... bars.

Does wind occur when you move up into higher air pressure from lower air pressure?
Yes, wind occurs when temperature and pressure differentiations meet eachother.
How do monsoons occur?
A monsoon occurs when hot air pressure and cold air pressure collide.
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 causes air pressure differences?
Unequal heating of the Earth - this causes Winds; because the air pressure has to where it can [is allowed to] go and that is why their are differences in air pressure. Low pressure systems are the active features of the Atmosphere - because High pressure systems occur wherever Lows do not.
Where do Precipitation and storms occur in?
Does precipitation and storms occur in high pressure sytems Precipitation and storms occur when cold air meets hot air. This can also happen when a cold front moves into a warmer area.
How does strong wind occur?
Strong winds occur when there is a steep gradient in air pressure, i.e. if the difference in air pressure is large, the air moves from the area of higher pressure to the area of lower pressure at a considerable rate, or velocity.
Does wind occur as air moves from a place of low air pressure to a place of high air pressure?
Yes
What kind of weather will occur in an area of high pressure air?
In a high pressure area, good warm weather will occur. In a low pressure area, colder rainy weather will occur.
What causes air pressure in the air?
It is the weight of the air itself that causes air pressure. Fluctuations occur due to changes in wind and temperature. We live in air pressure of about 15 pounds per square inch.
Does wind occur when you move up into higher air pressure from lower air pressure?
Yes, wind occurs when temperature and pressure differentiations meet eachother.
How do monsoons occur?
A monsoon occurs when hot air pressure and cold air pressure collide.
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 holds water in the air?
Air pressure holds water in the air. When the pressure builds up and the air gets too saturated to hold any more moisture, then precipitation will occur.
Why does wind occur when air tends to move from regions of higher to lower?
Pressure
What causes air pressure differences?
Unequal heating of the Earth - this causes Winds; because the air pressure has to where it can [is allowed to] go and that is why their are differences in air pressure. Low pressure systems are the active features of the Atmosphere - because High pressure systems occur wherever Lows do not.
Why do and breezes occur?
Convection currents cause the air to rise when heated. This causes the air pressure to become lower on the surface, which then pulls in air from nearby regions, which is felt as wind.
Where do Precipitation and storms occur in?
Does precipitation and storms occur in high pressure sytems Precipitation and storms occur when cold air meets hot air. This can also happen when a cold front moves into a warmer area.
