A barometer that uses mercury measures air pressure by monitoring the height of the mercury column in a tube. As air pressure changes, the mercury level rises or lowers in response. This instrument is called a mercury barometer.

there is a decrease in atmospheric pressure. Atmospheric pressure is directly proportional to the height of the mercury column in a barometer. When the height decreases, it indicates that the pressure in the atmosphere is lower.
low pressure system and stormy weather
A mercury barometer consists of a tall glass tube filled with mercury inverted into a container of mercury. The mercury in the tube will fall until the weight of the mercury column is balanced by the atmospheric pressure pushing down on the surface of the mercury in the container. The measurement is then taken from the height of the mercury column in the tube.
