NCAR ASP 2008 Summer Colloquium on Numerical Techniques for Global Atmospheric Models

A NCAR ASP summer colloquium entitled Numerical Techniques for Global Atmospheric Models was held in Boulder on une 2-13, 2008. The primary organizers were: Peter H. Lauritzen (CGD, NCAR), Christiane Jablonowski (University of Michigan), Mark Taylor (Sandia National Laboratories) and Ramachandran D. Nair (IMAGe, NCAR).  This site contains information that was used and generated at that colloquium.

Sponsored by NCAR ASP, NASA and DOE.

Output of nine models running test case 5-0-0 (Mountain-induced Rossby wave): 700 hPa zonal wind at day 15. The test starts with balanced and isothermal initial conditions. A 2-km-high Gaussian-hill-shaped mountain is placed at [90degE, 30degN] (not shown) to trigger Rossby waves. The test evaluates the treatment of the orography and reveals numerical noise (especially at later days). [Image courtesy of Christiane Jablonowski.]
