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.
The rainfall intensity tends to decrease as the duration of the rainfall increases. This is due to the nature of the storm and weather patterns, where short, heavy storms result in higher intensities than longer, sustained rainfalls.
Step 2: Analysis of options.
- (A) increases with increase in duration: Incorrect. Intensity decreases with duration. - (B) decreases with increase in duration: Correct. Intensity decreases as the rainfall duration increases. - (C) is independent of the duration of the rainfall: Incorrect. Duration affects intensity. - (D) sometimes increases and sometimes decreases with increase in duration: Incorrect. The general trend is a decrease.
Step 3: Conclusion.
The maximum rainfall intensity decreases with an increase in duration, so the correct answer is (B).
Final Answer: \[ \boxed{(B) decreases with increase in duration.} \]
