Opening · a definition

Cloudburst means more than 100mm of rainfall in a short span of time (30min to 1 hour) over a short region (30-60 km2) - IMD (Ministry of Earth science)

Body · points and prose

Cloudburst disasters (1) 2013 Kedarnath (2) 2021 Uttarakhand (3) 2025 Kinnaur, Himachal Pradesh & Chamoli, Uttarakhand

Causes of cloudburst

Diagram
Moisture laden airmass → stuck in mountain or valley → continuous updraft → cloud-too heavy particles → cloudburst

(1) Air masses - moisture laden and cold

(2.) Topography → mountain valley traps the airmass (3.) Regional climate eg. more incidents of cloudburst in India in monsoons

Implications in mountain regions of India

Positive (1.) Rejuvination of river streams (2.) groundwater recharge.

Negative (1.) Infrastructure damage → cloud burst → flash floods. eg. houses destroyed in Kinnaur 2025. (2.) Loss of life & morbidity (3.) Disruption to businesses.

Close · a way forward

Disaster causing cloudburst must be made predictable through localized weather station & big data analysis in future.
