  1. A barometer is a tool that measures atmospheric pressure, or the weight of air over a particular point. Barometers are widely used to forecast weather, because a change in atmospheric pressure indicates that a weather change soon will follow. When the barometer reading falls, it indicates low-pressure air, which usually means a storm is coming. When it rises, it means high-pressure air and fair weather.
