India sees driest August since 1901, Sept rains could be ‘normal’: IMD

After the driest August since 1901, the India Meteorological Division (IMD) held out some hope on Thursday, saying that the typical rainfall in September is predicted to be ‘regular’, within the vary of 91-109 per cent of the long-period common (LPA) of 167.9 mm.

September accounts for about 19 per cent of the whole seasonal rainfall.

Cumulatively, although, the unusually weak August month has ensured that even when the rainfall in September is in direction of the upper finish of the band (say round 109 per cent of the LPA), the seasonal rains could be ‘under regular’. For the June-September interval, rainfall between 96-104 per cent of the LPA is taken into account ‘regular’.

A revival of monsoon is badly wanted for standing kharif crops, particularly in states like Maharashtra, Madhya Pradesh, Gujarat, Rajasthan, Karnataka, and Telangana, which obtained scanty rainfall in August.

The all-India common rainfall in August was 161.7 millimeters, which was 36 per cent lower than regular — the worst since 1901. Additionally, there was 20 days of monsoon break in August, which was the very best since 1989.

Because of scanty rains, the all-India common imply and most temperatures in August 2023 had been the very best since 1901, and the minimal temperature was the second highest.

“There are three issues that make us optimistic about an uptick in rains in September. First, the variety of low strain programs over the Bay of Bengal is predicted to extend. Second, Madden Julian Oscillation (MJO) will probably be beneficial. Third, the Indian Ocean Dipole (IOD), which has been ‘impartial’ all by way of August, is poised to develop into ‘optimistic’ and stay ‘optimistic’,” IMD Director Basic Mrutyunjay Mohapatra stated at a digital press convention.

Mohapatra stated a revival of monsoon would start from round September 2, and it could progressively get higher.

Area-wise, the IMD stated above-normal rainfall was more than likely over many areas of northeast India, adjoining east India, foothills of Himalayas, and a few areas of east-central and south peninsular India. The remaining components may even see regular to below-normal rainfall.

Mohapatra stated there was no forecast of any early withdrawal of the southwest monsoon.

On El Nino, he stated it was strengthening and would develop into stronger with every passing week and stay in drive until early a part of subsequent 12 months.
