A pressure system is a region of the Earth's atmosphere where air pressure is a relative peak or lull in the sea level pressure distribution.The surface pressure at sea level varies minimally, with the lowest value measured 870.0 hectopascals (25.69 inHg) and the highest recorded 1,085.7 hectopascals (32.06 inHg).ain articles: Low-pressure area and Cyclone. A low-pressure area, or low, is a region where the atmospheric pressure at sea level is below that of surrounding locations. Low-pressure systems form under areas of wind divergence that occur in upper levels of the troposphere.
Absolute pressure: The total pressure exerted on a system referenced to zero Pascals, and equal to the gauge pressure plus atmospheric pressure; Gauge Pressure: Pressure referenced to one atmosphere, and is the pressure actually shown on the dial of a gauge that registers pressure relative to atmospheric pressure. For example, an ordinary pressure gauge reading of zero does not mean there is no pressure, it means there is no pressure in excess of atmospheric pressure. Atmospheric Pressure ...
