WarmWorld meets again! #MPIM_Scientists and their collaborators from across Germany are gathering this week to make our global storm resolving climate model #ICON even better!

Better at what I hear you ask? We have 4 key focuses: land-atmosphere interactions, turbulence, cloud microphysics and particles. Find out more on the #WarmWorld website: https://warmworld.de/

Tropospheric warming is usually treated as uniform across the tropics. However, in a recent paper, #MPIM_scientists show that the projected upper tropospheric warming in #ClimateModels is not spatially uniform. Using the classical Gill model, they demonstrate that the pattern of tropospheric warming is coupled to circulation and convective heating changes.

As we emit CO2, changes to the relative humidity of the mid-troposphere will strongly affect the strength of gloabl warming. But why do models struggle to consistently simulate relative humidity?
In their most recent paper, #MPIM_Scientists probe this question based on a series of sensitivity experiments #ICON in its storm-resolving configuration and find a surprising role of the turbulence parameterisation.

Paper alert ! 🚨
#MPIM_Scientists Philipp de Vrese et al. published a study on the importance of #permafrost hydrology in global climate simulations.

In a new study our #MPIM_Scientists Thomas Kleinen and Victor Brovkin, together with Sergey Gromov and Benedikt Steil of the Max Planck Institute for Chemistry simulated for the first time the evolution of #climate and methane for the entire period from the last #IceAge to today. In their groundbreaking study, they were able to show that the changes in #methane concentration since the last ice age were caused primarily by tropical wetlands.

New publication 📄

How does #tropical rainfall get partitioned between #land and #ocean? We can measure this partitioning, but that doesn't mean we understand what controls it.

#MPIM_Scientists Luca Schmidt & Cathy Hohenegger built a conceptual #model to investigate just that. They find that the ratio between land and ocean #precipitation is mainly controlled by the efficiency of #moisture transport in the #atmosphere, and less so by land surface processes.

The round-the-world racing event #TheOceanRace started in Alicante, Spain, yesterday. ⛵︎ Skippers will cross the North Atlantic in 5 legs over the next six months.

Skipper #BorisHerrmann is helping #MPIM_Scientists to gain a deeper understanding of the ocean 🌊 as a carbon sink by measuring #CO2 while competing in The Ocean Race. Godspeed! 🍀 #ARaceWeMustWin #Malizia #ClimateActionNow
