How does Barometric Pressure effect the weather?
Ive heard of what it does somewhat but Im not clear on it.

Like right now the pressure is 30.06 and rising.

If it is rising what does it mean or if it falls what does that mean?

If this is answered somewhere else your welcome to point me in the right direction!!! laugh.gif

Barometric pressure does not affect the weather. It is the weather that affects barometric pressure.

Imagine that you are standing at the bottom of a glass of water. The water represents the atmosphere. The barometric pressure on you, standing at the bottom of the glass, would be the force, measured in inches of mercury, the water is exerting on you, which is 30.06 in-Hg according to your sample. Since areas of low pressure evacuate mass from the center, the pressure is lower because the mass of the atmosphere above is less. Conversely, areas of high pressure add mass to their centers. If the mass of the airmass increases, so too does the pressure.

It gets more complicated from here.

So in laymans terms the barometric measure is the amount of pressure the atmosphere is exerting around and above us?
