Question

Intensity of drizzle is:

• A. Greater than 3 mm/h
• B. Between 1 mm/h to 2 mm/h
• C. Less than 1 mm/h
• D. Between 2 mm/h to 3 mm/h

Hint:

Drizzle has droplets \(\lt 0.5 \text{ mm}\) and intensity \(\lt 1 \text{ mm/h}\).
These parameters distinguish it from light rain (which has larger drops and higher intensity).

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
Precipitation is classified into rain, drizzle, snow, and hail based on droplet size and intensity.

Step 3: Detailed Explanation:
Drizzle consists of very small, numerous, uniform liquid water droplets with diameters less than \(0.5 \text{ mm}\).
Because of the tiny droplet size, the rate of accumulation is extremely slow.
The intensity of drizzle is characterized as:
- Light: \(\lt 0.25 \text{ mm/h}\)
- Moderate: \(0.25 \text{ to } 0.5 \text{ mm/h}\)
- Heavy: \(0.5 \text{ to } 1.0 \text{ mm/h}\)
Overall, the maximum rate of drizzle accumulation is less than \(1 \text{ mm/h}\).

Step 4: Final Answer:
The intensity of drizzle is less than 1 mm/h.
