| 摘 要： | 根据各收支方程讨论，概述了各研究者采用直接和间接的方法，计算得出长江流域梅雨期暴雨过程中各源汇的空间分布特征。虽然个例，地区和资料不同，其结果各有差异，易比较，但次网格尺度运动对不尺度环境场的反馈作用均非常显著，因而在设计暴雨预报的数值模式时，参数化方案是必不可少的。

| Abstract: | On the basis of discussion about various budget equations,the horizontal pattern and vertical profiles of apparent source and sink with direct and indirect methods over the Changjiang River basin during Mei-yu heavy rain are summarized. Although the results are different and difficult to compare for each case,region or data,but this is certainly followed by an important vertical transport process of subgrid-scale,which reflects the striking effect of cumulus convection on largescale environment.Thus,for any prognostic models of heavy rain over the midlatitutes,it is necesary to add the parameterization of subgrid-scale motion. |
