A devastating Cloud Burst swept over Leh on August 2010. Which one of the following statements with regard to Cloud Burst is not correct?

Result
Your answer: —  Â·  Correct: C
Explanation

A cloudburst is a localized weather phenomenon characterized by intense rainfall (often exceeding 75-100 mm per hour) over a small area in a short duration [2]. It occurs when moisture-laden air is forced upward rapidly, leading to the formation of cumulonimbus clouds [4]. While cloudbursts are highly frequent in hilly regions like the Himalayas due to orographic lifting [4], they are not exclusive to such terrains. Historical data confirms cloudburst events in non-hilly areas, such as the devastating Mumbai cloudburst on July 26, 2004 [3]. Therefore, the statement that they occur 'only' in hilly areas is incorrect. Furthermore, predicting these events remains a significant challenge for meteorologists because of their small spatial scale and sudden onset [5]. The Leh event of August 2010 is a classic example of such a high-intensity, localized disaster in a high-altitude desert [3].
