Our new paper on marine heatwaves in the North Indian Ocean is now published in Frontiers in Climate. We identify distinct modes of marine heatwave variability shaped by interactions between ENSO and the Monsoon Intraseasonal Oscillation. Read more: frontiersin.org/journals/clima…

🎉 Ligin’s second PhD paper is out in JGR: Oceans! We show that upper-ocean warming in the Arabian Sea persists despite declining surface heat flux, highlighting the role of ocean heat transport and convergence. 🤝@unisouthampton @NOCnews @iitbbs Link: doi.org/10.1029/2025JC…

Warm oceans seem to be turning even 'weak' cyclones into deadly rainmakers Even when storms are not especially strong in wind terms, the amount of rain they carry is increasing For every degree of global warming, atmosphere holds about 7% more moisture. phys.org/news/2025-12-o…

Unless we act responsibly to limit greenhouse gas emissions and become more resilient to the consequences of a changing climate, the season that sustains life across India may increasingly threaten it. scroll.in/article/108777… Ligin Joseph writes Via The Conversation

India’s monsoon is getting more extreme but with little increase in rainfall scroll.in/article/108777…

I wrote an article for @ConversationUK on this year’s extreme monsoon rainfall and its increasing trend.

New study:While June 2013 & July 2023 extreme rainfall events in North India had similar largescale circulation patterns, key differences exist - in evaporative sources, pathways, and jet stream interactions 1/2 @iitbbs @seocs_iitbbs @unisouthampton Link: link.springer.com/article/10.100…

Does an increase in AMOC variability signal an imminent tipping point? A recent article in GRL (@theAGU) explores how gyre circulation intensity can lead to false positives, with increased variance but no bistability. #AMOC #TippingPoints #Climate doi.org/10.1029/2024GL…

@unisouthampton has released a press statement on our latest research article about the increasing monsoon rainfall over northwest India! southampton.ac.uk/news/2024/10/r…. 📰 And here’s some media coverage of our findings: thehindubusinessline.com/economy/agri-b… krishijagran.com/news/climate-c… @fluidchaser

New research from @OceanEarthUoS has found a climate change contradiction in northern India. A big increase in summer monsoon rain is turning semi-arid regions wetter. It's the second piece of @unisouthampton research to hit the Indian press this week 📰 thehindubusinessline.com/economy/agri-b…

🌍 Global sea surface temperatures have been rising for decades. This radial plot shows monthly SST anomalies from 1982 to August 2024 (60°S-60°N), highlighting the increasing frequency of positive anomalies. Data: @NOAA OISST V2. #ClimateChange #OceanScience #GlobalWarming

The 2024 monsoon season concluded with 7.6% above-average rainfall. Here are the rest of the years for comparison. Thank you, @Hosalikar_KS for noting that some La-Nina years were missing in the previous post. #ClimateChange #Monsoon #ENSO #IOD #Rainfall @Indiametdept @LIJODXL

Our recent research on North-West Indian rainfall trend is featured on Hindustan Times @htTweets @lj3n23 @seocs_iitbbs @iitbbs @unisouthampton hindustantimes.com/editors-pick/g…

Congratulations @lj3n23 on getting featured in today's Hindustan Times newspaper. Proud moment! #monsoon #research #oceanography

2/2 It is always reassuring to know that we are in the right path to reveal the close-to-reality working mechanisms of our mother nature 😃

1/2 The current NW India heavy rainfall, SLP and wind patterns shows close resemblance with our recently published work at GRL (agupubs.onlinelibrary.wiley.com/doi/10.1029/20…) The Hadley cell expansion and Indian Ocean warming results in stronger trade winds and merging of it with monsoon Cross-Eq flow
