Question

The maximum rainfall intensity at a given location

• A. increases with increase in duration
• B. decreases with increase in duration
• C. is independent of the duration of the rainfall
• D. sometimes increases and sometimes decreases with increase in duration

Hint:

For rainfall, the intensity typically decreases as the duration increases, as it spreads over a longer perio(D)

Answer 1

The Correct Option is B

Step 1: Understanding Rainfall Intensity.
Rainfall intensity generally diminishes as the duration of the rainfall extends. This inverse relationship stems from the typical behavior of storms, where brief, intense downpours exhibit higher intensities than prolonged, steady rain.
Step 2: Analysis of options.
- (A) increases with increase in duration: Incorrect. Intensity shows a decrease as duration increases. - (B) decreases with increase in duration: Correct. Rainfall intensity decreases with longer durations. - (C) is independent of the duration of the rainfall: Incorrect. Duration demonstrably influences intensity. - (D) sometimes increases and sometimes decreases with increase in duration: Incorrect. The predominant pattern is a decrease.
Step 3: Conclusion.
As maximum rainfall intensity declines with increasing duration, option (B) is the accurate choice.
Final Answer: \[ \boxed{(B) decreases with increase in duration.}\]
