摘要
通过个例诊断分析,讨论了黄土高原上暴雨的对称不稳定性及其判据的分布特征,结果表明对称不稳定层结在此类天气过程中具有重要作用。计算表明,暴雨区的判据值是小于零的。
Based on case diagnosis we investigated the symmetric instability of a rainstorm over the loess plateau, along with the distribution of the criterion of the event. Results show that symmetrically unstable stratification is of importance to such a weather process and that the criterion is <0 in magnitude over the rainfall area.
