Best Answer

A barometer is used in 2 ways.

First you keep it stationary. You record the pressure. If the pressure drops, it means, a storm is coming.

Second, in a car or airplane when the barometer falls, it means you are getting higher. When the barometer drops, it means you are getting lower.

A Barometer measures Air Pressure. When using a Barometer, you can forecast storms, however you'll need radar to know where the storm is located. While Air pressure is low, that allows for cloud formation (Not necessarily storm clouds). While Air pressure is high, this doesn't allow for cloud formation.
