omega tau science & engineering podcast

[We have episodes in German and English] How do scientists uncover phenomena and explain their connections? How do engineers design machines, methods and infrastructure? At omega tau, experts give detailed answers. Over the last ten years, we have produced 300 episodes in which we dug deeper, until we ran out of questions. Join us on our journey through the world of science and engineering: the closer you look and listen, the more interesting things get.

episode 326: Weather Forecasting at the ECMWF


Guests: Hilda Carr, Peter Bauer, Tony McNally
Host: Markus Voelter    Shownoter: Thomas Machowinski

Earlier this year I visited the European Center for Medium-Range Weather Forecasts, a European organization that produces global weather forecasts and performs research on how to improve those. The episode has three parts. First, Hilda Carr gives us an overview of the organization, its purpose and its history. Then I talk with Peter Bauer 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 about where the ECMWF gets its data and how it is continuously fed into the “running” model.
