MISU guest seminar | Bjorn Stevens

Next Generation Climate Models

by Bjorn Stevens, Dir. for the Atmosphere in the Earth System at MPI, Hamburg

Time: 28 May 2019, 14h15–14h45
Venue: Rossbysalen C609, Arrhenius Laboratory, 6th floor

Abstract
Climate scientists have become so used to explaining how their models are based on fundamental laws and physical principles, we sometimes ourselves forget the crude approximations and seat-of-the-pants reasoning that underpins many of their important aspects. Advances in computing are however making it possible to revisit the climate modelling enterprise, to create models whose physical foundation is much stronger. In doing so we hope to mitigate against long standing and intractable deficiencies in present day climate models. In this talk I will try to explain why next generation climate models are much more than higher-resolution versions of existing models, what we hope to learn about the climate system from their capabilities, and why taking theses steps is so important.
