Abstract: Meso-scale heavy rain numerical model was studied.Regional atmospheric model parallel program with high hierarchy and modularity was built based on parallel applications infrastructure.With simulation of typical weather event, correctness, improvement of parallel performance and high-resolution simulation are tested.The new parallel model kept well prediction performance of original model and improved parallel performance and extendibility.The model simulated better with higher resolution.

Key words: AREM model, JASMIN framework, parallel computation, two-dimensional decomposition, parallel efficiency
