摘要
以自主研制的区域中尺度暴雨大气模式为研究对象,基于JASMIN并行编程框架,建立构件化、层次化的区域大气模式大规模高效并行程序,并针对典型天气实例,对模式并行计算程序的正确性、并行性能及高分辨率模拟效果进行验证.结果证明,基于JASMIN框架的新模式程序与原串行模式具有很好的计算一致性,其不仅能保持原有模式良好的预报效果,且能显著提升模式大规模并行计算性能和可扩展性,在进一步提高模式分辨率后能得到更好的预报结果.
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.
