中文摘要: 本文介绍了准地转Q矢量分析理论和方法,给出用Q矢量散度表示强迫项的准地转ω方程和Q矢量的物理意义。用Q矢量分析方法诊断了1987年8月4日在辽宁出现的一次强对流天气过程,并与数值预报结果进行了比较,结果表明,这种方法能够较清楚地揭示强。对流天气过程中大尺度环境场的变化。可以为业务预报提供一些有参考价值的信息。

Abstract:In this paper, the quasi-ge'ostrophic Q-vector analysis -method is introduced. B/ means of Q-vector analysis, we diagnosed a severe cbnvective storm episode (4-5 Augest 1987) in Liaoning Province and compared the diagnostic result with LFM Prediction. The results suggest that the Q-vector analysis can reveal the synoptic and sub-synoptic scale circulation change during the severe convection and provide some valuable information for local short range weather forecasting.
