Question

The type of rainfall is called heavy, when its intensity is:

• A. 1.5 mm/h to 2.5 mm/h
• B. 2.5 mm/h to 5 mm/h
• C. 5.0 mm/h to 7.5 mm/h
• D. More than 7.5 mm/h

Hint:

Understanding rainfall intensity classifications is crucial for hydrology and water resource management. These values are standard and frequently appear in exams.

Answer 1

The Correct Option is D

Step 1: Recall the meteorological classification of rainfall intensity. Rainfall intensity is a measure of the amount of rain that falls over time. It is typically measured in millimeters per hour (mm/h).
Step 2: Identify the threshold for heavy rainfall. Based on standard weather service classifications, rainfall is considered "heavy" when its rate of fall exceeds 7.5 mm per hour. Rates below this are categorized as moderate, light, or drizzle. This classification helps in forecasting potential flooding and other hydrological impacts.
