A Nine-layer Atmospheric General Circulation Model and Its Performance

Different versions of a new nine-layer general circulation model which is rhomboidally truncated it zonal wave number 15 (L9R15) are introduced in this paper. On using the observed global monthly sea surface temperature (SST) and sea ice (SI) data from 1979 to 1988 offered by the international Atmospheric Model Inter-comparison Program (AMIP), these different model versions were integrated for the ten-year AMIP period. Results show that the model is capable of simulating the basic states of the atmosphere and its interannual variability, and in performing reasonable sensitivity experiments
