| 摘 要： | 本文以7406与7411号台风登陆后出现突然性大风区引起突然性的暴雨中心为例,从能量的角度出发,对出现大风区引起暴雨中心的物理机制进行了计算分析,结果表明:当台风(指7406和7411号台风,下同)受干冷空气影响前后,有明显的能量转换,即有效位能向动能转换,正能量区对应大风区,大风区的辐合区对应于暴雨中心。这种配置关系是由斜压能量转换引起大风区产生的。

| Abstract: | In this paper,according to two landed (7406 and 7411) typhoo ndata, the main physical mechanism of the heavy rain center caused by strong wind region is analysed. The results show that there is evident conversion of energy when landed typhoon is affected by the dry cold air. It means that, there exists a conversion of the available potential energy to the kinetic energy, and the positive energy corresponds to the strong wind region and the convergence region of strong wind region corresponds to the heavy rain center. This relation is caused by the baroclinic energy conversion. |
