Summer monsoon starts retreating, regional climate outlook indicates normal winter monsoon in south | India News – Times of India


NEW DELHI: With clearly logging out as ‘above normal’ seasonal rainfall, the southwest monsoon on Monday finally started retreating from parts of west Rajasthan and Punjab on Monday against its normal withdrawal date of September 17. The withdrawal from parts of north and central India will happen in the next 2-3 days.
A regional ‘Climate Outlook’ for October-December period, meanwhile, predicted ‘normal rainfall’ for most parts of north peninsular India and ‘below normal’ rainfall for some parts of extreme south-eastern India in coming three months – an indication of overall ‘normal’ north-east (winter) monsoon in India.

“During the season, normal to slightly above normal temperatures are likely, over most parts of the region (south Asia),” said the regional ‘Climate Outlook’ for October-December period, released on Monday.
On withdrawal of south-west (summer) monsoon, the India meteorological department (IMD) said, “Conditions are becoming favourable for further withdrawal of southwest monsoon from some more parts of Rajasthan and Punjab, and some parts of Haryana, Chandigarh, Delhi, Uttar Pradesh and Madhya Pradesh during next 2-3 days.”

The withdrawal on Monday happened from Amritsar, Bhatinda, Hanumangarh, Bikaner, Jaisalmer and Lat.
The withdrawal of south-west monsoon from west Rajasthan this year is early compared to last year when it happened on October 9. In 2018, the withdrawal started on September 29, while it happened on September 27 in 2017, September 15 in 2016 and September 4 in 2015.
The ‘Climate Outlook’, released by the South Asian Forum comprises of nine countries and representatives from world meteorological organisation (WMO), predicted ‘below-normal’ rainfall during October-December period over the southern parts of the South Asia including some parts of extreme south-eastern India, most parts of Sri Lanka and Maldives, which climatologically receive good amount of rainfall during the season.
A consensus outlook for October-December season rainfall over South Asia has been prepared based on the expert assessment of prevailing large-scale global climate indicators such as the prevailing weak La Nina conditions in the equatorial Pacific Ocean and neutral Indian Ocean Dipole (IOD) conditions over Indian Ocean during the season.
“The relative impact of all these parameters needs to be considered to determine the expected state of the climate over the region during the season,” said the forum in its statement.
