摘要
总结了近年来我国学者关于边界层和陆面过程对中国暴雨影响的研究成果。此类研究主要应用中尺度数值模式,有的对边界层过程和陆面过程做敏感性试验,有的则对模式中边界层和陆面过程参数化作改进。结果表明:边界层和陆面过程对我国暴雨有明显影响。主要表现在影响暴雨的强度以及使暴雨中心位置有一定的变动,但决定暴雨发生发展的主要因子是大中尺度动力过程。对边界层和陆面过程的改进能有效改善数值模式对暴雨的模拟。
This paper summarized the research of the effects of PBL and land surface process on the heavy rain in China by Chinese meteorologists. This kind of research applied meso-scale numerical model to do sensitivity experiment for the PBL and land surface process,or improve their parameterizations. The results showed that there were obvious effects of PBL and land surface process mainly on the strength of the heavy rain and the location of the center of heavy rain system. But the main factor controlling the occurrence and developments of heavy rain is the dynamical process of macro- and meso-scales. The improvement on the PBL and land surface process models can improve the simulation of the heavy rain.
