Which of the following weather conditions is indicated by a sudden fall in barometer reading?
- AStormy weatherCorrect
- BCalm weather
- CCold and dry weather
- DHot and sunny Weather
Explanation
A sudden fall in the barometer reading indicates a rapid decrease in atmospheric pressure. This creates a low pressure area which causes surrounding high pressure air to rush in quickly. This movement of air, combined with rising warm moist air that cools and condenses, typically results in stormy weather, strong winds, and rain.
In contrast, a gradual fall usually indicates rain, a steady barometer indicates settled weather, and a rise in the reading signifies fair or clear weather. Therefore, a sudden and sharp drop is a classic precursor to a storm.
