Excess rain washes out IMD’s methods
The HinduWhile India this year may have recorded its highest monsoon rain in 25 years, an analysis suggests that new monsoon models, called the Monsoon Mission Coupled Forecast Model, deployed by the IMD over the last decade don’t do better than the older ones in long-range forecasting. The IMD’s workhorse statistical models said in its last update on August 1 that All India Monsoon Rainfall would be 96% of the LPA. So I'm surprised that they didn't warn of higher rains.” Highest since 1983 On August 1, the IMD said August and September rains would be “100% of what’s normal” for the two months with an error window of ±8%. On September 10, scientists at the Indian Institute of Science, Bengaluru, and the INCOIS, Hyderabad, said the monsoon rains in August and September would be “above normal” — based on data updated to August 10.
