Is tropical rain belt variability driven by self-organization of #clouds? ⛅️

We're proud to welcome Dr. Tomoro Yanase at #MPIM to investigate this question, together with #MPI_Scientist Cathy Hohenegger. 🌅

They aim to use both idealized & realistic simulations, & #ORCESTRA observations to understand how variations in SST patterns may cause variability in cloudiness across the #ITCZ 🌧️🌊🌍

Dr. Yanase’s #ResearchStay is supported by the @HumboldtStiftung & will last for 1 year from Oct 2025 🙌

🌦️ Observations show that the most intense rainfalls in the Intertropical Convergence Zone occur near its southern edge. Using storm-resolving #ICON simulations from @nextgems_eu #MPIM researchers Divya Sri Praturi & Bjorn Stevens have explained how this asymmetry arises. The study provides valuable insights into the dynamical mechanisms that shape the #ITCZ & provides new constraints on how far north the ITCZ could shift in a warming world. 🔗 https://mpimet.mpg.de/en/communication/detail-view-news-homepage/what-drives-the-asymmetrical-structure-of-the-intertropical-convergence-zone

Doing @SkepticalScience New Research is feeling very "On The Beach" these days.

Obvious mortality is delayed not by the #ITCZ but by the publishing pipeline.

#Schmelzwasser aus der #Antarktis schwächt die atlantische #Umwälzströmung (#AMOC) schwächt. Das #Schmelzwasser gelangt über den #Südpazifik und die #DrakePassage in den #Nordatlantik, wo es den #Salzgehalt reduziert. Gleichzeitig verschiebt sich durch die Kühlung im #Südpolarmeer die innertropische #Konvergenzzone (#ITCZ) nach Norden, was mehr Regen im tropischen Atlantik verursacht.

Was Virginia Woolf talking about the ITCZ when she said “the inner life has its soft and gentle beauty”?

J. Windmiller and B. Stevens are exploring the inner life of the #ITCZ in the hope of better understanding its outer life. They're revealing the rich, asymmetric, structure of it—much more fascinating than the single line that is often falsely assumed. Read their paper: https://t.ly/2RK_G.

And watch this space! The upcoming #ORCESTRA campaign in August will certainly have more to say.

The FS Maria S. Merian completed the third and last crossing of the #ITCZ during the campaign MSM 114/2. During ten days, Julia Windmiller and Laura Köhler from the Max Planck Institute of Meteorology and Daria Paul and Lennéa Hayo from the University of Cologne sampled three vertically resolved profiles of the ITCZ with #radiosondes.

News from our scientists Julia Windmiller and Laura Köhler: “Yesterday in the morning at 8 am we turned around for the second time to start our third and last crossing of the #ITCZ. We already measured two very nice profiles to study the inner structure of the ITCZ. To better understand the edges of the #Atlantic ITCZ, we sampled the northern edge tonight.”

Launching radiosondes at 2 am and celebrating incoming rain — welcome to the world of our scientists Julia Windmiller and Laura Köhler!

They are currently on the move with the #ship campaign MSM114/2 on the research vessel Maria S. Merian. In the next days, they will sample profiles of the innertropical convergence zone — the equatorial zone where the trade winds converge.

'North Atlantic cooling triggered a zonal mode over the Indian Ocean during Heinrich Stadial 1'

"...the impacts of these forcings on coupled ocean-atmosphere interactions over the IO highlights the sensitivity of zonal asymmetries and their importance to future changes in tropical precipitation patterns."
