0 the amount of force at any point on the earth's surface caused by the weight of the air -- 大气压力，气压
The central barometric pressure continued to fall despite the fact that the storm was beginning to weaken.
Air at barometric pressure contains 21% oxygen combined with nitrogen and a mixture of other gases.
At a given barometric pressure, independent of temperature, the dew point determines the specific humidity of the air.
December 1990 storm, the 1976-1978 period, the 1949 blizzard, or even further back were broken, with barometric pressure records falling as well.
At the time, the barometric pressure was 988 mbar, and the eye was 20 miles (32 km) in diameter.
The density differs between mine gas mixtures and air influence movements, as do variations in barometric pressure.
All stations measure wind speed, direction, and gust; barometric pressure; and air temperature.
The measurements taken include temperature, barometric pressure, humidity, wind speed, wind direction, and precipitation amounts.
