Marginal rain revival this week may not offset monsoon deficit: Skymet

Rainfall is expected to make a marginal recovery this week, but it may not be enough to offset August's 40% deficit in regional rains, private weather forecaster Skymet said.

Barring Northwest India, the remaining three regions are facing rainfall deficiency as El Nino gathers strength and Indian Ocean Dipole (IOD) climate pattern index remains neutral. Madden Julian Oscillation (MJO) is seen to contribute to El Nino as it gains strength in  the coming weeks.

MJO, a global scale feature of the tropical atmosphere, is also fluctuating in the tropical weather on weekly to monthly time scale. MJO effects are most evident over the Indian Ocean and Western Pacific Ocean.
