| 摘 要： | 本文选取１９９１年７月５日２０：００－６日２０：００梅雨锋上移动性次天气尺度涡旋引起的长江中下游特大暴雨为实例。采用准拉格朗日球坐标系的旋转风和辐散风动能方程，计算得到次天气尺度涡旋发展和成熟两个阶段对流层各层旋转风动能和辐散风动能的收支特征为：在对流层高层（１００－４００ｈＰａ）两个阶段的旋转风动能源汇相同，辐散风动能源汇有异，即水平动能通量项和“摩擦”项符号相反；在中层（４００－７００ｈＰａ）

| Abstract: | Base on the budget equations of KR and KD in quasi-Lagrange coordinates system,the energy budgets of subsynoptic scale vortex in the developing and mature stages are computed The results show that in above stages the source and sink of KR and KD are same in the lower,the source and sink of KR is same and KD is different in upper the source and sink of KD is same and KR is different in middle troposphere |
