UPSC Prelims PYQ 2002: Causes of Thundercloud Development
Consider the following climatic and geographical phenomena:
- Condensation
- High temperature and humidity
- Orography
- Vertical wind
Thunder Cloud development is due to which of these phenomena?
- 1 and 2
- 2, 3 and 4
- 1, 3 and 4
- 1, 2, 3 and 4
Explanation
Option (d) is correct
- Thunderclouds (cumulonimbus clouds) develop under conditions of high temperature and humidity, which promote rapid uplift of warm moist air. Orographic uplift caused by mountains and strong vertical air currents also aid cloud formation. As the rising moist air cools, condensation occurs, leading to the development of thunderclouds accompanied by heavy rain, lightning, and thunder.
Answer: (d) 1, 2, 3 and 4
