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).

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 ...

A chart shows the expected impact of Houston’s atmospheric pressure on “aches and pains” this week. (KIAH) What impact does weather, particularly atmospheric or low barometric pressure, ...

Atmospheric pressure, also known as barometric pressure, drops as a storm system approaches. In Florida, where low-pressure systems are common, the link between these drops and physical discomfort ...

The lowest pressure I've seen recently was 29.00 at SEATAC Wednesday at 11pm. That is low, but not the lowest seen in this area. The Hanukkah Eve storm in 2006 produced barometric pressure ...

This chart (below) converts pounds per square inch, or psi, into the SI unit. The official SI unit for pressure is the Pascal (Pa = N/m2 = kg/ms2) or kiloPascal (kPa = 1000 Pa). SI is an abbreviation ...

(KIAH) — Are those aches and pains you’re feeling the result of a change in the weather? For some, fluctuations in temperature or atmospheric pressure could be the source of unexpected ...
