Meteorologists measure changes in air pressure using barometers. High- and low-pressure weather systems move across the country, resulting in changes to barometric pressure. atmospheric pressure, force per unit area exerted by an atmospheric column (that is, the entire body of air above the specified area). Atmospheric pressure can be measured with a mercury barometer (hence the commonly used synonym barometric pressure ), which indicates the height of a column of mercury that exactly balances the weight of the ... Barometers. Barometers are instruments that measure the pressure of air in a specific environment; barometer measurements are used to forecast weather and measure altitude. Atmospheric pressure also depends on the planet’s mass, its surface radius, the gas concentrations and composition, and the gases’ vertical distribution in the atmosphere.Atmospheric pressure or barometric pressure is the pressure within the atmosphere of Earth.
