An area is considered to have high barometric pressure when it has greater atmospheric pressure than the surrounding area. Normal barometric pressure is between 980 millibars and 1,050 millibars. High pressure systems ar... More »

Normal barometric pressure is typically around 101.325 kPa / 1013.25 mbar / 760 mmHg / 29/921 inHg. Pressure rarely increases or decreases more than 1 inch of mercury (3.386 kPa / 33.86 mbar / 25mmHg) above or below the ... More »

Barometric pressure was discovered in about 1644 when physicist and inventor Evangelista Torricelli invented the first mercury barometer. Torricelli was an assistant to Galileo Galilei who suggested that Torricelli try u... More »

A barometric pressure sensor measures pressure differences in the atmosphere. In automotive applications, this reading is used by the powertrain control module to regulate engine timing and fuel trim. More »

The six basic elements of weather include temperature, humidity, atmospheric pressure, wind, precipitation and cloudiness. When combined, these elements can describe the weather conditions extant. More »

Isobars are lines on a weather map that represent areas with equal atmospheric pressure. Each isobar line follows a path through locations with an equal atmospheric pressure that is plus or minus four starting with 1000 ... More »
