It is the changing weather. High pressure situations are generally associated with fair, sunny weather. As high pressure is an area of sinking air, and air tends to dry out as it sinks, leaving sunny skies.
Low pressure areas are generally cloudy or rainy areas, where strong areas of low pressure bring our stormiest weather. That is because it is an area of rising air, and as air rises, it condenses into clouds and rain.
Air moves from higher pressure to lower pressure, so if you have a high and a low nearby, it can be windy as air rushes between the two.

∙ 12y agoPressure can change as a result of:
-Change in Temperature
-Change in Volume
-Change in number of Moles
This is based on the formula: PV = nRT
where:
P is pressure
V is volume
n is number of Moles
R is a constant
T is temperature

Changes in density (more or less water vapor), changes in temperature, tides (even air masses are affected Earth's rotation, the Moon and the Sun).

How does air pressure change in a tornado?
The air pressure should be lower inside than outide
How and why does the air pressure change as you climb up a mountain?
all the air pressure goes down, so as you get higher up, there is less in the air
Does air pressure change wind?

How does density change as air pressure increases?
If you have air in a tight cylinder piston system, when you apply pressure you will see the volume of the air reduced. The amount of mass of air is the same, but now it occupies less volume, the molecules are closer together, its density has increased.
What is a pressure gradient and how is it related to air movement?
Pressure gradient is the rate of pressure change as you change position, not just the difference between the lowest pressure and the highest pressure, but how great (or small) the physical distance between them. Since it the pressure difference that make air flow (wind) the greater the pressure gradient, the greater the wind.
How does air pressure change as altitude change?
Increased altitude means decreased air pressure.
A change in can bring about a change in air pressure?
if the dna sequence of a gene was tacttaccgagctagact then what kind of mutation has occured This has nothing to do with the question of air pressure. Either a change of temperature or a change of volume can affect air pressure, according to Boyle's Law of Gases. Increasing temperature=increased air pressure Decreased volume=increased air pressure The reverse is also true. Decreased temperature=decreased air pressure Increased volume=decreased air pressure
How does air pressure change as air is heated?
Air pressure decreases.But when air gets colder it increases.
How does air pressure change as you move up in the atmosphere?
the air pressure increases
How does air pressure change as you move up the atmosphere?
the air pressure increases
Can you see air pressure change?
No. You can see it expand the object that is containing the air as the air pressure increases.
Does air pressure change with altitude?
The higher up you are the lesser the air pressure in the atmosphere.
How can you die from a rapid change in air pressure?
Sudden change in air pressure might lead to death. Sudden change in air pressure will disrupt the blood and air circulation within your body. You might feel dizzy and have nose-bleeding in such cases.
Why does the air pressure change the altitude in the atmosphere?
As the amount of air above us decreases...the air pressure decreases.
Does the air pressure change during the formation of a hurricane and why is that important?
yes the air pressure changes
How does air pressure change in a tornado?
The air pressure should be lower inside than outide
As altitude increases how does air pressure change?
Increased altitude means decreased air pressure.
