| 摘 要： | 根据ＫＲ和ＫＤ方程的各项水平分布，着重讨论伴有暴雨和不伴有暴雨两类低空急流维持的动力过程，指出主要差异在于维持机理不同，尤其是能量转换方向相反，从ＫＤ和ＫＲ的正转换似乎是暴雨发生的必要但非充分条件，同时能量转换的强度和方向不仅决定于涡度场和散度场的相对配置，还与急流的垂直分布形式直接有关。

| Abstract: | Coupled equations of rotational and divergent Kinetic energy are used to study the mechanisms for generating and maintaining low-level jets in two real cases with and without heavy rain. As they are accountable by the relative height at which upper and lo |
