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.
A barometer
An advantage of using a barometer is that you can measure air pressure.
I think it is a barometer and aneroid barometer
Air pressure
"barometer"
A a radar is better: it can detect a tornado at a distance. A barometer would be of no use unless the tornado came dangerously close.
A barometer
No, pressure differences will be too localized...unless the tornado is on top of you.
barometer is used to measure air pressure
A barometer is an instrument used to measure atmospheric pressure. A circle does not have a barometer!
A barometer measures wind speed
No, a barometer measures pressure.
A barometer is an instrument used to measure atmospheric pressure.
A balloon barometer measures atmospheric pressure.
Barometer
The barometer is the instrument that is used to measure the air pressure.
Usually the instrument used is called a barometer- which could be a closed end manometer or an aneroid barometer.An altimeter actually also measures atmospheric pressures - but for a different purpose.
