Title : NCAR climate model developments with focus on dynamics, consistency and coupling to parameterizations
Name of the speaker : Peter Hjort Lauritzen
Affiliation : National Center for Atmospheric Research (NCAR)
Laboratory organizer : LMD
Date and time : 12-06-2014 10h00
Location : Ecole Polytechnique, Palaiseau - LMD - salle de réunion du LLR au 1er étage
Summary :

Many modeling groups are transitioning to global atmospheric models discretized on non-latitude-longitude grids. This has encouraged dynamical core developers to return to the drawing board and develop new fluid flow solvers. An overview of this transition process and ongoing developments of the NCAR CAM (Community Atmosphere Model) will be given. Special attention will given to numerical aspects such as efficient and consistent tracer transport, variable resolution, angular momentum conservation, and new topography generation software that directly accommodates unstructured grids.
