Abstract

The global/regional assimilation and prediction system of a new generation developed by China Meteorological Administration(CMA)was introduced. The main characteristics of the system were discussed, such as full compressible and hydrostatic/non-hydrostatic approximation in option, global/regional unified model, semi implicit-semi Lagrange decretization scheme, standardization, modularization and parallelization of the model software, etc. GRAPES has been applied in national and regional meteorological centers, universities and research institutes.
