Air pressure
I think it is a barometer and aneroid barometer
A barometer is an instrument used to measure atmospheric pressure. It can measure the pressure exerted by the atmosphere by using water, air, or mercury. Pressure tendency can forecast short term changes in the weather. Numerous measurements of air pressure are used within surface weather analysis to help find surface troughs, high pressure systems, and frontal boundaries.See the related link .A barometer measures air pressure.A barometer is an instrument that is used to measure atmospheric pressure.
An advantage of using a barometer is that you can measure air pressure.
If a tornado passes near or over a barometer, it will measure a very rapid drop in pressure. How much the pressure drops depends on the strength of the tornado and how close the center of it comes tot he barometer.
