Latsis symposium held in ETH-Zurich
The Latsis symposium 2019 has been held in ETH-Zurich during August 21st-23rd with the aim to join the computer science and high-resolution modelling communities to tackle some of the biggest challenges faced nowadays in climate science.
The event was fully successful, with more than 100 people attending for sharing their knowledge and research to a large international audience of scientists.

How close are we to global km-scale weather and climate simulations?
28.05.2018
A recent study of a team of MeteoSwiss, ETH and C2SM researchers, led by Dr. Oliver Fuhrer, investigates how close we are towards achieving global km-scale weather and climate simulations. A baseline of what is achievable today is established using a fully refactored model code on Europe’s largest supercomputer Piz Daint at the Swiss National Supercomputing Centre CSCS in Lugano. Link
A decade long Convection-Resolving Climate Simulation on the European Scale

*This paper has been selected as a publication highlighted by AGU’s Earth & Space Science News (Link)
For the first time, a decade-long convection-resolving climate simulation has been conducted for continental-scale computation domain located over Europe. The results show the robustness of the improvements in the representation of summer convection, and demonstrate that convection-resolving climate simulations on a continental-scale computational domain are feasible. Exploiting the capabilities of new supercomputers that mix conventional multi-core CPUs and accelerators contains the computational costs while providing a reasonable time to solution. Link
Climate goals and computing the future of clouds
04.01.2017
How clouds respond to warming remains the greatest source of uncertainty in climate projections. This paper discusses how high-resolution atmospheric models can reduce this uncertainty. It is argued that a combination of approaches will be needed, among these the exploitation of limited-area high-resolution models to improve parameterization schemes. For more details see
Towards European-Scale Convection-Resolving Climate Simulations
21.09.2016
In the paper published by D. Leutwyler et al., the applicability of the convection-resolving climate simulation approach has been demonstrated on European scales with a new version of the COSMO weather and climate model, capable of running on GPUs. The simulations demonstrate how the approach allows for the representation of interactions between synoptic-scale and meso-scale atmospheric circulations, and that results (regarding diurnal cycle of summer precipitation) found in previous studies also apply to European-scale domains.
