Monsoon hits Kerala and Northeast | Monsoon reached Kerala and Northeast two days before normal, IMD issued a statement regarding rain

On Thursday, May 30, the monsoon has knocked simultaneously in Kerala and most parts of Northeast India. It has knocked two days before its normal date of June 1. The normal date for the onset of the monsoon in Kerala is June 1, after which it moves northwards, usually at a rapid pace, and covers the entire country around July 15. The monsoon normally arrives in Northeast India around June 5. But, during some years when the Bay of Bengal monsoon is active, the monsoon also arrives in Northeast India at the same time.

“The monsoon system over the Bay of Bengal is very active due to the severe cyclone Ramal, which has pulled the monsoon current into the region. The northeastern states have received very heavy rainfall in the last two days,” IMD Director General M Mohapatra said. Apart from this, in the last two days all the criteria for the arrival of monsoon in Kerala are being fulfilled.”

If after May 10, at least 60% of the 14 stations – Minicoy, Amini, Thiruvananthapuram, Punalur, Kollam, Allapuzha, Kottayam, Kochi, Thrissur, Kozhikode, Thalassery, Kannur, Kudlu and Mangalore – report 2.5 mm or more rainfall for two consecutive days, the onset of monsoon over Kerala is declared on the second day, provided the wind pattern is south-westerly and the outgoing longwave radiation (OLR) is low. OLR represents the total radiation emitted by the atmosphere into space or the extent of clouds.

The advance of the southwest monsoon over the Indian mainland is marked by the onset of monsoon over Kerala and is an important indicator signifying the transition from the hot and dry season to the rainy season. As the monsoon advances northwards, the regions get relief from the scorching heat With 47% of the country’s population dependent on agriculture for their livelihood (according to this year’s Economic Survey), a bountiful monsoon is directly related to a healthy rural economy.

The IMD, in its long range forecast on April 15, said monsoon rainfall over the country between June and September is likely to be “above normal” at 106% of the long period average (LPA), with a model error of ± 5%.
