Heat waves Present episode of high temps expected to continue in entire Ind-Gangetic plains a few more days with temps crossing 45 C Models predict a delayed monsoon onset over north India but with some uncertainties Cooler temps over Peninsula due to expected monsoon rains

Monsoon Update: After a normal progress, monsoon is going into a hiatus mode. Not much progress expected next 8-10 days, thus delaying onset over north India. This cause extreme temps & heat waves over north India, including Delhi, UP and Bihar. Follow India Meteorological Department

Monsoon update: Models (ECMWF India Meteorological Department) suggest after a hiatus in its advance, monsoon is reviving during last week of June, will advance further & cover the whole country by July first week. Really a good news, but forecast uncertainty remains. La Nina on its way too.

Such hiatus is very common in the monsoon season…We need to wait for the next spell to revive the monsoon. That’s expected during the last week of June. Anyway, June will be deficient. But we should not worry…… We will have a normal #monsoon: Madhavan Rajeevan

Monsoon Update: After its revival, monsoon will progress further & cover whole country by 5 July. Active monsoon phase expected next 2-3 weeks with heavy rains along west coast & north India. High probability of extreme rains & flooding in north India. We should be alert..

Monsoon update: Monsoon will be in active phase next 10-12 days with monsoon systems forming over Bay of Bengal. Heavy rains expected over Odisha AP Maharashtra & Gujarat. Subsequently, we should expect a weak monsoon in the early part of August. La Nina is yet to develop..

Today is 18th Foundation Day of MoES GoI Wish all the best for ongoing & future programs. Excellent contributions from MoES GoI weather & climate services DOM & blue economy Ocean & polar explorations monitoring earthquakes Bringing a lot of nostalgia.. Ravi Gopal Iyengar

There are some special people who guide us in our professional journey, set aside time to teach us and answer our silly questions. Dr Madhavan Rajeevan is one such special guide in my life. I have learnt so much from him. Happy birthday, Dr Rajeevan. Thank you for always guiding me🙏

Finally, Nino 3.4 index is negative, indicating the onset of La Nina event. Climate models however did not do well in predicting this La Nina event. Indian monsoon should respond positively to this La Nina development.. MoES GoI

Though an ‘orange alert’ — which means “be prepared for action and do not wait for a red alert” — is adequate to galvanise actions on the ground to minimise the impact of extreme weather events, experts have flagged the REAL PROBLEM… Read what Madhavan Rajeevan has to say:

Other factors that may have contributed to Wayanad’s “increased susceptibility” to landslides, plus high casualties? A 62% forest cover loss and warnings that did not outline specific impacts. "Human intervention played an important role, there's no doubt about it": Madhavan Rajeevan

A well written article on Wayanad disaster and climate change attribution study by the UK group.

Very sad to inform Prof Eugenia Kalnay is no more One of the brightest meteorologists, known for famous NCEP/NCAR reanalysis data & most cited research paper (35000) MoES GoI had active collaboration with her through 2 big projects under the Monsoon mission. Rest in peace.

Why is monsoon rainfall declining over Indo-Gangetic Plains (IGP)? “Firstly, there is a delay in monsoon depression formation. Secondly, there is a decreasing frequency of monsoon depressions which give rainfall over IGP” -- Madhavan Rajeevan Read full report: shorturl.at/jPttp

Monsoon Update Surprising to see the system over N Arabian sea is intensifying into a cyclonic storm. In text books we learnt that N Arabian sea becomes colder during the season due to ocean upwelling & no system can intensify Effect of global warming? Need to understand better

Very excited to visit Ashoka University to give a 3-hour tutorial on Monsoon Modelling for students Discussed present skill in monsoon prediction & scope of AI/ML methods to improve monsoon prediction More focused AI/ML research is required to improve monsoon prediction MoES GoI

My article in FE on observed long-term changes & how monsoon will change in a warmer climate We need to sensitize farmers & water resource managers & help them prepare adaptation measures. "Business as usual" can be disastrous. financialexpress.com/life/science-g… MoES GoI PMO India
