Why does high pressure mean nice weather and low pressure mean rain? Weather you'd like to know. Published: ; Sep. 29, 2016, 8:30 a.m.

The Pressure Gradient Force, Coriolis Force, and friction all act on wind. These forces cause air to spread out from high pressure systems and move toward low pressure systems.

MILWAUKEE -- Probably, at some point in your life, you've seen a weather map similar to the picture below. It has red Ls and blue Hs all over the place, representing low and high pressure.

The turning of the earth creates a force called the Coriolis force; that's responsible for the air moving around high and low pressure systems. Because the air within a "high" is sinking, ...

High pressure systems are often associated with clear skies and sunshine because the clockwise-circulating systems push air downward, causing winds to blow away from the system’s center.

Dear Tom, I have noticed that warm and cold fronts are always connected to low pressure centers but not to highs. Any explanation? — Sharon Walker Dear Sharon, A “front” is a boun… ...

When there is high pressure, the atmosphere has a surplus of air. The atmosphere likes to be in equilibrium (or balanced). As a result, air rushes in and converges on areas of low pressure.

Air pressure is one of the main building blocks of weather because areas of different pressure help drive the changes you see in the weather. To demonstrate high pressure, push your hands down on ...

In the case of an upper level low, think of that low pressure starting on the 10th floor, higher up. They setup high in the atmosphere and influence weather below.
