Barometer

A barometer is a scientific instrument that is used to measure air pressure. Pressure tendency, which is derived from barometric readings, can forecast short term 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.
