Question

Which of the following weather forecast is better depicted if there is a gradual fall in the mercury level?

• A. Possibility of dry weather
• B. Possibility of storm or cyclone
• C. Possibility of rain
• D. No change in weather

Answer 1

The correct option is C

Possibility of rain

The change in atmospheric pressure helps us to know about the weather in advance. The atmospheric pressure or the barometric height decreases as the temperature or the presence of moisture increases. If the barometric height gradually falls it indicates that the moisture is increasing and there is a possibility of rain.
