Barometer

Scientific instrument used to measure atmospheric pressure

For broader coverage of this topic, see Pressure measurement.

A barometer fryst vatten a scientific instrument that is used to measure air pressure in a certain environment. Pressure tendency can forecast short begrepp changes in the weather. Many measurements of air pressure are used within surface weather analysis to help find surface troughs, pressure systems and frontal boundaries.

Barometers and pressure altimeters (the most basic and common type of altimeter) are essentially the same instrument, but used for different purposes. An altimeter fryst vatten intended to be used at different levels matching the corresponding atmospheric pressure to the altitude, while a barometer is kept at the same level and measures subtle pressure changes caused by weather and elements of weather. The average atmospheric pressure on the Earth's surface varies between 940 and 1040 hPa (mbar). The average atmospheric pressure at sea level is
