India Meteorological Department (IMD) on Monday predicted that the monsoon would be ‘normal’ through August-September. However, a attainable emergence of La Nina in the Pacific Ocean from October may possibly prolong the monsoon season and bring in more rains through the harvesting period, potentially damaging some kharif crops, analysts warned.
“The 2021 August-September rainfall over the country as a whole is likely to be normal and quantitatively 100% of the Long Period Average (LPA),” IMD director common Mrutyunjay Mohapatra mentioned at an on the internet briefing. Rainfall among 95% and 105% of LPA is thought of ‘normal’ for the two months. The LPA (1961-2010) through the August-September period is 428.3 mm. During August, monsoon rainfall is most likely to be 99% of LPA, Mohapatra added.
‘Below normal’ to ‘normal’ rainfall has been predicted more than quite a few places of the north-west, east and north-east India, the important paddy and sugarcane increasing regions. ‘Normal’ to ‘above normal’ precipitation is seen more than most components of peninsular India, home to plantation crops like rubber and coffee, and soybean, cotton and pulses increasing central area through August-September.
Pan-India precipitation was 1% under the benchmark (LPA) through June-July, even although there was a 7% deficit in July, the wettest of the 4-month season that is critical for summer season crop sowing. The precipitation was 10% above LPA in June. Normally, 65% of the sowing requires location in July although the remaining 35% of 107-million-hectare standard kharif acreage gets covered in June and August-September.
As most of the international models forecast the emergence of the La Nina situation from October-November (at present ENSO neutral), there could be more rains in India through that period, which may well adversely influence crops prepared for harvesting.
Last year, the monsoon retreated from the nation on October 28, the second-most delayed exit considering the fact that 1975, and as a outcome, soybean crops got broken by heavy rains in Madhya Pradesh through September-October. In 2010, the southwest monsoon withdrawal got completed on October 29. The standard monsoon withdrawal date is October 15. Coincidentally, each 2010 and 2020 had Lal Nina.
Since 2016-17, the country’s foodgrains output (comprising rice, pulses and coarse cereals) through kharif season has been hitting new records every single year. During the 2020-21 kharif season, the production was 148.4 million tonne, 3.2% greater than a year ago.
El Niño, which is related with warmer-than-typical sea surface temperatures in the central and eastern tropical Pacific Ocean, generally brings decrease monsoon rainfall. It develops when the surface temperatures of the Pacific rise above standard. La Nina is opposite of El Nino and happens when sea surface temperatures in the Pacific Ocean drops under typical.
Though the stalling of the monsoon for the 3 weeks till July 11 adversely impacted sowing, there has been a choose-up of the activities more than the previous week, particularly in main crop-generating regions. So, sown places reached 79% of the season’s standard acreage of 107.3 million hectares as on Friday as against 67% a week prior to of course, the region below crops was nevertheless 5% under the year-ago level.
