Welcome to the Center for Climate Systems Modeling (C2SM). C2SM is a research center based at ETH Zurich. It is a joint initiative between ETH Zurich, MeteoSwiss, Empa, WSL, and Agroscope with the main objective to improve the understanding of the Earth’s climate system, and our capability to predict weather and climate.
|12 February 2015 - Using the COSMO model in a convection resolving configuration (horizontal grid spacing of 2.2 km), Nikolina Ban and colleagues have found that projected increases in both extreme daily and hourly summer precipitation in summertime over continental Europe follow theoretical expectations from the Clausius-Clapeyron relation. These results are in contrast to previous studies that predicted an increase of extreme hourly precipitation faster than expected from the Clausius-Clapeyron relation. Ban, N., et al. (2015): Geophysical Research Letters, doi:10.1002/2014GL062588 For more details: see the CSCS highlight|
|5 February 2015 - Dr. Katherine Silverthorne Osterried has joined C2SM in February. As the successor of Anne Roche, she will lead the C2SM activities related to regional climate modeling. Katherine holds a bachelor's degree in mathematics and received a PhD in Geophysical Fluid Dynamics from MIT in 2010. She then joined Queen’s University in Belfast, where she developed and implemented numerical methods that extend the well known TELEMAC suite of CFD solvers, and collected experience in software development and user-support. We wish Katherine a warm welcome!|
|16 December 2014 - Antarctic sea-ice cover has increased over the past few decades. C2SM community member Alexander Haumann led a team of scientists that explained the underlying cause and analyzed why climate models fail to reproduce it. The authors found that winds blowing more strongly away from the Antarctic continent were the driver of increasing ice cover. Consequently the ice is further blown to the north and the ocean refreezes in the south. However climate models do not fully reproduce this effect. Haumann and colleagues argue that the model they used in their study does not capture the influence of the smaller scale topography around the continent and surface processes over ice and snow accurately enough. These processes influence the surface-pressure distribution and hence the direction of the wind. Thus, once the model shows a more realistic atmospheric circulation in Antarctica, the simulations of the sea-ice trends will likely improve.|
|28 November 2014 - Nitrogen concentrations have increased markedly in surface waters across the North Pacific Ocean for the past decades. C2SM member Nicolas Gruber was part of a team of researcher that reconstructed these changes. The trend could enhance microbial growth in the ocean and eventually increase production of the greenhouse gas nitrous oxide (N2O). Read more in ETH-News (in German).|
|23 September 2014 - A collaborative effort between C2SM associated scientists at ETHZ (Oliver Stebler, Urs Beyerle and Reto Knutti) and at MeteoSwiss (Oliver Fuhrer and Reto Stöckli) has resulted in a very impressive visualization of a high-resolution (1.1 km, 2 min) simulation produced by the experimental weather model COSMO-1 that is currently developed at MeteoSwiss. This visualization was nominated as the second best visualization presented at the recent The Platform for Advanced Scientific Computing (PASC) Conference.|
|18 August 2014 - There is little evidence for a systematic overestimation of the temperature response to increasing atmospheric CO2 concentrations in a large number of climate models (CMIP5 ensemble). This conclusion by Markus Huber and and C2SM member Reto Knutti was published in recent study in "Nature Geoscience" that looked for explanations why global mean surface warming over the past 15 years has been less than in earlier decades and than simulated by most climate models. The authors found that internal variability (El Niño/Southern Oscillation, ENSO) and updated solar and stratospheric aerosol forcings from observations can explain the cooling. An adjusted climate model of reduced complexity was shown to be consistent with the temperature record of the past 15 years. Read the complete study here and see the article in ETH-News (in German).|
|24 July 2014 - Two Sinergia projects funded by the Swiss National Science Foundation were recently awarded to teams that include members of C2SM including Ulrike Lohmann , Christoph Schär and Heini Wernli. The goal of the project „Cloud-resolving climate modeling on future supercomputing platforms” (crClim) is to develop and exploit a European-scale climate model that is capable to resolve convection at a grid-spacing of 2 km. This endeavor needs close collaboration between atmospheric, climate and computer sciences from ETH, MeteoSwiss and the Swiss National Super Computing Center CSCS. The project “Paleo Fires” has the overall objective to advance the understanding of linkages between climate, land use, fire and vegetation. Participants from ETH IAC, PSI and the University of Berne want to focus on different regions over the most recent period of the last 150 years in comparison to the previous 2000 years.|
