As highlighted in a recent issue of DOE Pulse, which features science and technology news from the DOE National Labs, scientists from Pacific Northwest National Laboratory (PNNL) have developed a more efficient way to perform computationally expensive global climate simulations. As climate models become more precise and detailed, the simulation takes more time, putting pressure Read more…

Fortunately, the latest improvements to high-resolution climate simulations are not only improving the fidelity of the models, but are also deepening our understanding of climate dynamics, both qualitatively and quantitatively.
Some of the most important supercomputing models aimed at climate change research have been developed by National Oceanic and Atmospheric Administration (NOAA), and in particular, its Geophysical Fluid Dynamics Laboratory (GFDL) at Princeton University. The GFDL researchers are experts in climate science, but as with many scientists, are often less adept with the vagaries of supercomputing technology. That’s where HPTi comes in.
The first international effort to bring climate simulation software onto the next-generation exascale platforms got underway earlier this spring. The project, named Enabling Climate Simulation (ECS) at Extreme Scale, is being funded by the G8 Research Councils Initiative on Multilateral Research and brings together some of the heavy-weight organizations in climate research and computer science, not to mention some of the top supercomputers on the planet.
The challenge of climate change brings out the worst in us.
Climate researchers tap idle PCs.
Cheaper to house NCAR super out-of-state.
In Offenbach, Germany, researchers at the German Meteorological Service work around the clock forecastings storms, rain and hail showers — weather conditions that usually arrive on very short notice. In order to make these seemingly unpredictable events somewhat less so, the German Meteorological Service has installed a new NEC supercomputer.
