Q42 (CAPF/2024) Geography › Indian Physical Geography › Indian rainfall patterns

Which one of the following statement with reference to hailstones is NOT correct?

Result
Your answer: —  Â·  Correct: C
Explanation

Statement 3 is incorrect because it describes the formation of sleet, not hailstones. Sleet forms when raindrops or partially melted snow fall through a warmer layer aloft and then refreeze into ice pellets in a subfreezing layer near the surface [3]. In contrast, hailstones form within dense cumulonimbus clouds when strong updrafts carry raindrops into extremely cold, subfreezing upper regions of the atmosphere [1][3][4]. Regarding other options, hailstones are indeed associated with cumulonimbus clouds [1][4] and typically exhibit multiple concentric layers of ice due to repeated circulation above and below the freezing level [1][2][4][5]. In the Indian context, hailstorms are practically absent during the monsoon season, as they are more frequent in pre-monsoon summer months when atmospheric instability is high [2]. Therefore, the mechanism described in option 3 is the defining characteristic of sleet rather than hail.
