大气稳定度指数ZI及其在对流性天气预报中的应用

STABILITY INDEX ZI AND ITS APPLICATION IN THE FORECASTING OF CONVECTIVE EVENTS

本文设计一个便于计算的新大气稳定度指数ZI,讨论了它的热力学含义和动力学特征以及对对流性天气过程的指示意义,提出一种预报对流性天气的方法。并结合近两年华东地区的4次强对流天气过程, 证明这种预报方法有一定的实用价值。

In tkis paper a new stability index ZI is designed for convenience of calculation. Its thermodynamic implication, dynamic feature and indicative significance to the convective weather process are discussed. A method of Convective weather forecasting is thus given, which is proved to be of practical value in the four severe weather occurrences in East China in recent two years.
