NEW DELHI: Heavy Climate change India received around 16 per cent more rainfall than normal in August, and above-normal rains are expected to continue through September for the third time in as many months this year. India Meteorological Department (IMD) on Monday forecasted above normal monsoon rainfall in most parts of the country during September, while heavy to very heavy showers are likely over some states like Uttarakhand and Rajasthan along with isolated extremely heavy falls that may lead towards floods and landslides.
Rain Forecast by IMD for September Below Normal
The monsoon will not be strong, on the other hand it does fall under ‘below normal’ category in more radical fashion areas like north Bihar, northeast UP and most parts of NE India- you can also see extreme northwest India too and major portions of south peninsular India.
However, the La Nina phenomenon has not yet formed. Now it is expected to get formed by Sept-end and hence, this will have no influence on the ongoing rainy season as even if gets develop till that time summer monsoon may be in withdrawal phase.
During Sept-Nov the La Nina weakens northeast (winter) monsoon in southeast India.
Though it is to soon to tell what effect this will have. By end-September, we would be in a position to say anything on this. IMD director general Mrutyunjay Mohapatra said, “We will also be witnessing cyclonic conditions due to the La Nina.
Besides, the August rainfall over Northwest India was 253.9 mm which is second highest during all these years with any preceding Jan-Aug seasonal total since 2001, as per the IMD’s statement on Saturday. At a virtual press conference, IMD Director General Mrutyunjay Mohapatra said the country received 287.1 mm of rainfall in August as against the normal of 248.1 mm
India as a whole has got 749 mm of rainfall, compared to the normal average rainfall rate of 701mm since June1 remaining till today.
IMD Predicts Extended Monsoon Season with Climate change Heavy Rains in September
Climate change Importantly, one of the reasons it could worry is that withdrawal of rains may delay in 2024. In the press conference, IMD said that it was also likely to delay monsoon withdrawal in 2024. Accounting for close to three-quarters of $3.5 trillion economy, the annual monsoon puts in almost one-half (like 47%) of needed rain that helps sow farms and refill reservoirs and aquifers. Irrigation levels up nearly half the country´s rice paddies Å Nearly 50% of farmland in India is rain-fed, and much more water comes from irrigated sources as well.
Heavy Rainfall Alert: IMD Forecasts More Downpours Climate change in September
Since most of the low-pressure systems moved south as their usual trajectory, this delayed rainfall to access many districts in the Himalayan hill States and northeastern region: due to which rain-to-rain spreading didn’t influence these areas also monsoon trough stay mostly perpendicular towards its normal situation.
A large part of northeast alongwith Kerala and Vidarbha region in Maharashtra, received rainfall ‘deficiently’ last year, he noted.
As many as six low-pressure systems were formed in August, two of which intensified into monsoon depression or deep depression,” the IMD chief noted. August: 17 days this August, normal is 16.3 low-pressure system days;
During August 10–22, the monsoon trough generally lay along its normal position and good rainfall occurred over northern as well adjoining central parts of India with some activity in east & northeast India but it was mainly dry. at most places elsewhere last week; The same supported above-normal precipitation-wise performance particularly for forecastable region covering northwestern plains (NP), Punjab-Haryana-Delhi-Chandigarh-west-Uttar Pradesh- south Haryana-south Rajasthan-north Gujarat,.
Also excessive activities started appearing from northeastern states to cover entire MP by next couple of weeks maintaining deficient signals there on further reduction around prevailing rain season end peak days though apart from those these features remained normal therefore ideally so acceptable! has been spelt out initially thus intensity increasing unprecedentedly year after years continuously should be witnessed during forthcoming fortnight while decrease will mark three sections making up overall monsoonal patterns meaning livelihood loss between country areas;
. Global warming The trough, which had been located slightly south of its normal position between August 23 and August 31 caused some very heavy rainfall to occur across parts of central & western India.
