KEY POINTS
Significance
· India receives rainfall during two seasons. About 75 per cent of the country’s annual rainfall is received from the Southwest monsoon between June and September.
· The Northeast monsoon, on the other hand, occurs during October to December, and is a comparatively small-scale monsoon, which is confined to the Southern peninsula.
· Also called the winter monsoon, the rainfall associated with the Northeast monsoon is important for Tamil Nadu, Puducherry, Karaikal, Yanam, coastal Andhra Pradesh, Kerala, north interior Karnataka, Mahe and Lakshadweep.
How has the Northeast monsoon season been so far this year?
· The India Meteorological Department (IMD) had forecast below normal rainfall over Tamil Nadu and normal rainfall over the southern peninsula for the current season.
· This year, the Southwest monsoon withdrew completely from the country on October 28, with a delay of a fortnight. On the same day, the IMD declared the onset of the Northeast monsoon over peninsular India.
· Officials at IMD have linked it to the prevailing La Niña conditions in the Pacific Ocean for deficient rainfall from northeast monsoon this year.
How is La Niña linked with the Northeast monsoon?
· While La Niña conditions enhance the rainfall associated with the Southwest monsoon, it has a negative impact on rainfall associated with the Northeast monsoon.
· During La Niña years, the synoptic systems low pressure or cyclones formed in the Bay of Bengal remain significantly to the north of their normal position. As they lie to the north of their normal position, not much rainfall occurs over southern regions like Tamil Nadu
· The current position of the Inter Tropical Convective Zone (ITCZ) has also contributed to the poor rainfall during the ongoing monsoon season. Currently, the ITCZ is located to the north of its normal position.
· La Niña conditions are expected to prevail until early 2021, with some weather models forecasting it to last even till March. As a result, there are high chances that the southern peninsular region may end up with deficient rainfall by the end of the Northeast monsoon season in December.
