The research by Hyderabad based INCOIS scientists on Cyclone Tauktae (2021) provides critical insights into storm intensification near India’s west coast.
- ‘Tauktae’, that had occurred in the Arabian Sea during May 14–19, underwent rapid intensification and was the deadliest with more than 120 people losing their lives and 1.1 million people affected in 421 villages.
Key Findings on Tauktae’s Rapid Intensification
- Atmospheric & Land Heating: Unusually high temperatures on land (more than 25°C) and intense atmospheric heating contributed significantly.
- High Humidity & Ocean Heat: Elevated sea surface temperatures, ocean heat potential, and moist soil conditions fueled the storm’s strength.
- La Niña & Negative IOD Effects: These climate oscillations played a role in increasing relative humidity, intensifying the storm’s impact.
- Atmospheric vs. Oceanic Contribution: The study found the atmosphere’s role (54%) was slightly more significant than the ocean’s role (46%) in intensification.
