Scientists will be able to study events such as tropical storm Karl, which developed in the Atlantic in September 2016, using the OpenIFS
OpenIFS at ECMWF has teamed up with the University of Oxford e-Research Centre to enable scientists to run the OpenIFS weather model on thousands of people’s home computers. The OpenIFS

“By exploiting the distributed computing power provided by tens of thousands of volunteers, CPDN can run weather and climate experiments that would be too computationally demanding even for supercomputers,” he points out. David explains that such computing power is required when scientists want to run thousands of slightly perturbed versions of a model for the same event. Studying Karl“Very large ensembles of weather and climate simulations are essential to study the predictability of extreme events,” says Antje Weisheimer, an ECMWF scientist who also works at the University of Oxford.
“This storm attracted a lot of interest among researchers studying the reasons for weather forecast busts in Europe,” Antje says. “In order to study the predictability of such storms and their impact on subsequent weather in Europe, we need to run thousands of slightly perturbed simulations, and this is where CPDN comes in.” The OpenIFS workshop from 17 to 21 June is devoted to the impact of moist processes on weather forecasts and will include work on Karl. On 18 June, David opened an OpenIFS experiment on Karl to some 8,000 CPDN volunteers who have Linux capabilities on their computers. At the end of the week, the results will be compared with the outcome of a similar experiment run on ECMWF’s high-performance computing facility. New possibilities
OpenIFS “The project offers unprecedented possibilities for users of OpenIFS,” says Glenn Carver, who leads the OpenIFS project at ECMWF.
Glenn Carver and his team have worked closely with the e-Research Centre at the University of Oxford to get OpenIFS
“If they have limited access to supercomputers or wish to carry out experiments with very large ensembles, OpenIFS
But he adds that the maximum horizontal resolution is expected to increase in the future. “As the computing power of home computers increases, it should become possible to carry out higher-resolution experiments using OpenIFS
Sarah Sparrow, the Programme Coordinator for the CPDN project, notes that OpenIFS “We had some discussions on the need to move towards a multi-model capability, and OpenIFS seemed like a good choice to expand the CPDN model portfolio.”
“Contact with the OpenIFS team at ECMWF was made through Antje, who is based in the Department of Physics at the University of Oxford as well as at ECMWF. The collaboration with ECMWF has been excellent and we look forward to OpenIFS
ECMWF Director of Forecasts Florian Pappenberger welcomed the availability of OpenIFS on CPDN. He said: “I’d like to thank all those involved for the work that has gone into this project. OpenIFS
