Dear Tom, My basement sump pump will sometimes run even when there hasn’t been rain for days. Does barometric pressure affect underground ground water levels? — Tom Simcoe, Palos Heights Dear ...

If one looks at the table at the top of this blog, you see that all the lowest pressure records for the Western Pacific occurred prior to 1987 (with the possible exception of Typhoon Mike).

As air gets warmer it expands and becomes less dense, causing atmospheric pressure to fall. In addition, air within the atmosphere can rise and fall, changing the atmospheric pressure.

One of my engineering references detailing a standard atmosphere table shows that normal pressure at sea level is 29.92 inches of mercury. This decreases to 25.84 inches at 4,000 feet and 24.90 at ...
