The northeast monsoon is usually volatile, but meteorologists say a long-range forecast of such intense rainfall in a short span needs scientific advances
The northeast monsoon of 2021, which is yet to withdraw, has brought abundant rain to the city. While spells of heavy rain are common during the monsoon, two spells of intense and unprecedented rain in a short span in November and December caught the city and meteorologists off guard.
This monsoon brought copious rain to Chennai without any major weather system.
The 148.5 cm rain received between October and December led to a surplus this season. This monsoon broke records and Chennai’s annual rainfall in 2021 was one of the highest — 226 cm as against the normal of 140 cm, surpassing the 2015 record of 209.5 cm.
