While air can be compressed more easily than water, freely flowing air acts much like waterâat least at relatively low speeds. So when you squeeze a stream of air, two things happen. The air speeds up, and as it speeds up, its pressureâthe force of the air pressing against the side of the objectâgoes down. When the air slows back down, its pressure goes back up. Why does the air speed up? Because of conservation of mass, which states that mass is neither created nor destroyed, no matter what physical changes may take place.
When the air is warm and wet, the barometer reading falls. When the air pressure falls, it usually indicates some type of storm or wet weather is coming.When it rises, it often means clear weather. If the barometer remains steady, there will be no immediate change in the weather. rising barometer indicates increasing air pressure; a falling barometer indicates decreasing air pressure. Years ago the French scientist and philosopher Blaise Pascal, discovered that air pressure decreases with height, and pressure changes at ground level at any one place can be related to daily weather changes.
