326 - Weather Forecasting at the ECMWF

Guests: Hilda Carr (linkedin.com/in/hilda-carr-77417a22/?originalS…), Peter Bauer (ecmwf.int/en/about/who-we-are/staff-profiles/p…), Tony McNally (ecmwf.int/en/about/who-we-are/staff-profiles/t…)

Host: Markus Voelter Shownoter: Thomas Machowinski

Earlier this year I visited the European Center for Medium-Range Weather Forecasts (ecmwf.int), a European organization that produces global weather forecasts and performs research on how to improve those. The episode has three parts. First, Hilda Carr (linkedin.com/in/hilda-carr-77417a22/?originalS…) gives us an overview of the organization, its purpose and its history. Then I talk with Peter Bauer (ecmwf.int/en/about/who-we-are/staff-profiles/p…) about weather and climate modeling and about encoding these models efficiently in software programs that run on supercomputers. Part three is a conversation with Tony McNally (ecmwf.int/en/about/who-we-are/staff-profiles/t…) about where the ECMWF gets its data and how it is continuously fed into the “running” model.
