Rise in Extreme Rainfall Events on India’s Southwest Coast
A recent study, titled ‘Deciphering the Relationship Between Moisture Flux and Monsoon Extreme Rainfall Over the West Coast of India,’ published in January 2025, revealed a steady rise in extreme rainfall events on India’s southwest coast.
Key Findings
- The study observed an increase in extreme rainfall events at a rate of 0.23 mm per season along the southwest coast.
- This trend is strongly linked to the thermodynamic component of moisture flux, which correlates with rising sea surface temperatures (SSTs) in the southeast Arabian Sea.
- The research analyzed monsoon rainfall data from 1990 to 2023, using observational records, reanalysis data, and SST trends.
