The Regional Meteorological Centre, Chennai has announced that NE monsoon ceased over the south peninsular region.
Though the season was interspersed with gaps in rainfall, the movement of weather systems kept the monsoon active.
This is one of the rare years when the monsoon prolonged till January end.
Normally, the monsoon withdrawal would occur in between December 26 and December 30 every year.
Tamil Nadu received nearly 58.9 cm of rainfall against its average share of 44.3 cm of rainfall during the core October and December monsoon months.
The State experienced the most delayed monsoon of 1933-34 on January 28.
The previous year’s season spilled over to the next calendar year during one-third of the years since 1901.
Monsoon had retreated from the State during the first 10 days of January during 28 years since 1901.
This weather phenomenon of extended monsoon has become more frequent since 2011.
Unlike Southwest monsoon, NE monsoon also called retreating monsoon, did not have a dramatic change in weather parameters like reversal in wind flow pattern during withdrawal.
The Dip in rainfall was one of the major criteria taken into account for monsoon retreat.
