Arabian Sea Mini Warm Pool

The Arabian Sea Mini Warm Pool forms every April–May near the Kerala coast with sea surface temperatures above 30°C.
This warm pool triggers local convection and helps attract south westerly monsoon winds toward the Indian subcontinent.
El Niño events delay the Indian Summer Monsoon by disrupting wind patterns in the Pacific and Indian Oceans.
The Indian Ocean Capacitor Effect causes a delayed warming response in the Indian Ocean 4–5 months after El Niño.
Easterly winds reduce surface cooling, intensifying the Mini Warm Pool in the southeastern Arabian Sea.
A stronger warm pool generates low pressure that pulls moist winds toward Kerala, supporting a timely monsoon onset.
In 2010, despite a strong El Niño, the monsoon arrived early due to this warm pool, as shown by IIT Delhi simulations.
