A sudden fall in barometer reading is typically indicative of stormy weather.
Explanation:
A barometer is a device used to measure atmospheric pressure. Changes in atmospheric pressure are closely associated with changes in weather conditions.
A sudden fall in barometer reading suggests a rapid decrease in atmospheric pressure. This decrease is often caused by the approach of a low-pressure system, which is commonly associated with stormy weather conditions. As the low-pressure system moves in, it can bring with it cloud formation, strong winds, and precipitation, leading to storms, rain, or other severe weather events.
Therefore, a sudden fall in barometer reading is commonly observed prior to stormy weather.
