Air Pressure Units Weather. Pressure gradient force causes the wind to blow. Meteorologists measure air pressure in units called atmospheres (atm). millibar values used in meteorology range from about 100 to 1050. pressure is the driving force of the weather phenomena. the general rule of barometric pressure is simple: High pressure typically portends hot, dry weather while low pressure portends cool, damp weather. an atmosphere (atm) is a unit of measurement equal to the average air pressure at sea level at a temperature of 15 degrees. At sea level, standard air pressure in millibars is 1013.2. Weather maps showing the pressure. atmospheric pressure is the force per unit area exerted by a body of air above a specified area (called an atmospheric column). Pressure has an effect on temperature. As air pressure changes, the height of the mercury column does as well, much like a thermometer. Mercury barometers measure the height of a mercury column in a vertical glass tube. air pressure is measured with mercury or aneroid barometers. As air cools it descends, leading to high pressure at the.
