| 摘 要： | 利用PSU/NCAR的非静力中尺度MM5V3模式,对2004年9月四川省及重庆市一次特大暴雨过程进行了凝结潜热与地表热通量的敏感性试验,结果表明:凝结加热与地表热通量通过影响中尺度系统环境场的高低空急流、高低层辐合辐散等动力、热力条件,从而影响中尺度系统的发展以及中尺度暴雨的发生。

| Abstract: | The nonhydrostatic mesoscale numerical model MM5V3 is used to simulate the heavy rainstrom Sichuan provine and Chongqing city from 00:00 on 3 to 00:00 on 5 September 2004,and do the sensitivityexperiment of condensation heating and surface sensible and latent flux.It found that the condensation heating and the surface sensible and latent flux which is important for extremely heavy rainfall,bying enhancehigh-level and low-level jets,high level convergence and low level divergence and so forth in the mesoscale system surroundings,in order to affect the developmentof the mesoscale system and the occur of the mesoscale heavy rain. |
