摘要
中尺度数值预报模式是进行中尺度天气预报的有效手段。中尺度模式MM5是国际上应用最广泛的中尺度预报模式之一。数值天气预报的巨大计算量和实效性要求必须通过高性能分布式并行计算来实现。分析了MM5串行算法的特点,研究了其并行算法的实现,讨论了算法的一些改进,给出了MM5模式在分布式并行巨型计算机上的测试结果。
Mesoscale numerical weather prediction model is the efficient way to the weather forecast. MM5 model is the most popular mesoscale model in the world. It is necessary to implement by means of high performance distributed parallel computation because of the large amount of calculation. This paper analyzed the sequential algorithm, studied the implement of the parallel algorithm, discussed some improvements, and presented some results of the experiment of MM5 implemented on the distributed parallel computer.
