摘　　要：为了将中尺度大气模式MM5应用到并行和网格计算领域,对中尺度大气模式MM5的原理进行研究,搭建了并行和网格环境,给出了需要的组件和配置流程,对网格和并行计算进行了比较.结果表明,CPU个数不再是提升MM5运行效率的瓶颈;在网络环境较差的条件下,gridftp比ftp更安全和稳定.In order to implement MM5 module in traditional parallel computing and grid system,MM5 was studied. Operational environment of MM5 and parallel computing were constructed. Essential condition and configuration procedure were given. Parallel computing was compared with MM5 by experiments. Results show that number of CPU is no longer the bottleneck of running MM5.Gridftp is more safe and stable than ftp under bad network computing environment.
