🚨Workshop alert🚨
High and Ultra-high Resolution Modeling of the Earth System
April 13-15, 2026, in College Station TX.

sites.google.com/tamu.edu/tam...

The Texas Center for Extreme Weather is hosting a workshop on:

High and Ultra-high Resolution Modeling of the Earth System

April 13–15, 2026 at Texas A&M University, College Station, Texas

The current generation of earth system models used by the IPCC have proven useful in simulating and projecting global temperature change. However, deficiencies and biases persist in these projections, especially at regional and local scales. The typical spatial resolution of these models (~100 km) is too coarse to resolve regional details and fine-scale storm systems. The next generation of earth system models is targeted at resolutions ranging from high-resolution (~10–25 km) where frontal systems can be simulated and ultra-high resolution (~3 km) where clouds begin to be resolved. Modeling at these resolutions poses significant scientific and computational challenges, but it can provide important benefits for societal applications.

Topics to be discussed in the workshop will include:

· Status of current high/ultra-high resolution earth system modeling efforts, including the NSF MESACLIP, StormSPEED, and MPAS-related projects from TAMU and NSF NCAR

· Future directions and challenges in increasing model resolution

· Applications of fine-resolution simulations for problems relevant to society, including extreme weather, hydrology, and regional planning

Registration and abstract submission details may be found on the workshop website: https://sites.google.com/tamu.edu/tamu-hires-workshop-2026

Please contact R. Saravanan (sarava@tamu.edu) for more information.

As Simple as Possible: The Importance of Idealized Climate Models - Eos

As models that simulate Earth’s climate system become increasingly complex, the use of simpler and more flexible idealized models remains important for science and education.

Not really sure if this is the right place to advertise a postdoc position related to high resolution models and high clouds (renewable for up to 6 years!), co-supervised by @aikovoigt.bsky.social and myself, but let's try to make this place a bit more lively, at least :)

New paper in ERL! We study the importance of resolution for the representation of climate extremes.

We use a new generation of km-scale models to show that many important details about temperature and precipitation extremes are hidden at CMIP6-like resolutions.

We are extremely grateful to @vscluster.bsky.social to allow us to teach our students on state-of-the-art HPC infrastructure. This is so much fun, and the students and we as lecturers really enjoy it. This semester, we are running ICON climate simulations to compare to digital twins.
