青岛市8.26暴雨中的物理量特征分析

通过对青岛市2003年8．26日暴雨个例的能量特征分析，发现本次暴雨过程的能量场中，中低空能量锋区、高能舌和高湿舌特征明显，能量积累过程明显；暴雨前6h和18h近地层都有逆温层存在，而低空去暖盖机制形成后，暴雨过程即开始；K指数很高，但暴雨前6h沙氏指数Si出现正值；单站资料垂直能量廓线的指示意义与以往总结的结论发生冲突；不同海域近海的风，尽管风向一致，但风速差异很大，最大风速和极大风速均出现在暴雨过程的前12h。

ANALYZING OF ENERGY CHARACTERISTIC ABOUT QINGDAO 8.26 RAINSTORM

From Qingdao 8.26 Rainstorm's energy characteristic of low and middle level, energy front, high energy tongue and humidity tongue are found clearly. 6 hours and 18 hours before the rainstorm, inversion layer is found in ground surface, and when the inversion layer is destroied, rainstorm begin. Single station data shows information that againsts some old conclusions. Offing wind in different sea area, have same direction but much different speed, and all maximum speed appears 12 hours before the rainstorm begin.
