In my latest article for @uk.theconversation.com, I break down how warmer oceans, higher evaporation, slow storm motion, and coastal proximity can turn even weak cyclones into intense rainmakers.
Cyclones Ditwah and Senyar show we must prepare for storms that are weak in wind but extreme in rain.
Warm oceans seem to be turning even ‘weak’ cyclones into deadly rainmakers

Wrote an article for The Conversation on this year’s extreme monsoon rainfall and its increasing trend.
It summarizes some of the major flooding events this year, explores their causes, and discusses the long-term trend in extreme monsoon precipitation over India.

Wilder, not wetter: climate change means extreme downpours are becoming far more common.
Why India’s monsoon is becoming more extreme – even though overall rainfall has hardly increased

Interactions between subpolar and subtropical jet streams lead to extreme rainfall events over the North Indian Subcontinent in June 2013 and July 2023 - Climate Dynamics
North Indian Subcontinent (NIS) is prone to disastrous and life-threatening floods during the summer monsoon period primarily due to its close proximity with the Himalayan foothills. Indian Meteorolog...

🌍 Global Sea Surface Temperatures (SST) are steadily rising 🌊.
This radial plot shows monthly SST anomalies averaged over 60°S–60°N. Each ring = a year, and segments = months, highlighting the growing intensity of positive SST anomalies due to climate change.

The 2024 Southwest Monsoon in India recorded 7.6% above the Long Period Average (LPA), marking an 'excess rainfall' year. This visualization shows monsoon trends over decades, revealing fluctuations influenced by ENSO and IOD phases.
