摘要
应用线性拟合方法,分析了长江中下游地区大范围暴雨前期低层流场共26个实例,结果表明线性量中形变量应予以重视,而非线性量S 对环境场初始扰动的形成密切有关,故可作为暴雨诊断量之一.
The 26 cases of lower lever winds over the Mid-Lower basin of YangtzeRiver are analysed.It shows that we should pay attention to the analysis ofdeformation field within linear quantity and the S=(?)term have significant effects on the formation of lower level initial disturban-ces.Therefore the author suggests that it can be one of the important physicalquantity for daignostic heavy rain processes.
