IMD Tracks Withdrawal of Southwest Monsoon Amid Regional Deficit

The India Meteorological Department (IMD) announced the official commencement of the Southwest Monsoon withdrawal from parts of northwest India. Concurrently, IMD data revealed that despite seasonal progression, nearly 43% of the country's meteorological sub-divisions continue to experience significant rainfall deficits at the end of the monsoon cycle.

The Southwest Monsoon typically advances across India between June and July, accounting for over 70% of the country's annual rainfall. The process of withdrawal begins when specific meteorological conditions are met, marking the transition toward the post-monsoon season and the eventual arrival of the Northeast Monsoon.

For IMD to declare monsoon withdrawal, three mandatory criteria must be satisfied: cessation of rainfall activity over the region for five consecutive days, establishment of an anti-cyclonic circulation in the lower troposphere, and a notable reduction in atmospheric moisture content.

Understanding monsoon dynamics is vital for assessing agricultural productivity, water reservoir levels, and macro-economic stability in India. This topic directly connects to UPSC GS Paper I (Physical Geography - Monsoon systems) and GS Paper III (Agriculture & Irrigation), frequently tested via analytical MCQs.
