When the barometer is dropping, it indicates that the air pressure is decreasing, which suggests that a low-pressure system or a weather front is moving in. This can often lead to cloudy or rainy weather as the atmosphere becomes less stable.

Why are rapidly dropping temperatures are accompanied by rising barometer?

Rapidly dropping temperatures are often associated with high-pressure systems moving in, which can cause the barometric pressure to rise. This occurs as the cold air descends and compresses, leading to a denser air mass and higher pressure readings on the barometer.

What happens to an aneriod barometer when air pressure changes?

When air pressure increases, the aneroid barometer contracts, causing the needle to move clockwise or indicate a higher pressure reading. Conversely, when air pressure decreases, the aneroid barometer expands, causing the needle to move counterclockwise or indicate a lower pressure reading.
