| Zusammenfassung |
| The Icosahedral Shallow Water Model (ICOSWM) has been a first step in the
development of the ICON (acronym for ICOsahedral Nonhydrostatic) models. ICON
is a joint project of the Max Planck Institute for Meteorology in Hamburg
(MPI-M) and Deutscher Wetterdienst (DWD) for the development of new unified
general circulation models for climate modeling and numerical weather
forecasting on global or regional domains. A short description of ICOSWM is
given. Standard test cases are used to test the performance of ICOSWM. The
National Center for Atmospheric Research (NCAR) Spectral Transform Shallow
Water Model (STSWM) has been used as reference for test cases without an
analytical solution. The sensitivity of the model results to different model
parameters is studied. The kinetic energy spectra are calculated and compared
to the STSWM spectra. A comparison to the shallow water version of the
current operational model GME at DWD is presented. The results presented in
this paper use the ICOSWM version at the end of 2008 and are a benchmark for
the new options implemented in the development of the ICON project. |
