In an uncommon phenomenon, La Ninã conditions prevailing over the equatorial Pacific Ocean since September 2020 have entered the third year.
La Ninã is when the sea surface temperatures (SSTs) along the central and equatorial Pacific Ocean are colder than normal, which, favours the Indian summer monsoon.
- However, La Niña years are also infamous for frequent and intense hurricanes and cyclones in the Atlantic Ocean and the Bay of Bengal.
The opposite is El Niño, that is, warmer SSTs prevail over these regions.
