摘要
本文利用常规资料、T213格点资料，对造成2003年8月24日～9月7日陕西省持续性暴雨、大暴雨过程的主要影响系统高空急流、低空急流的天气学、动力学特征及其与暴雨关系进行了分析，结果表明，在这次持续性暴雨过程中，高空急流及其南亚高压与低空偏南风或急流的有利配置是次级环流得以维持、对流持续和重建的重要机制。
Using the conventional data and grid data of T213 ,this paper analyses the synoptic and dynamic features of the upper-level and the low-level jet streams which are the main influential systems giving rise to the heavy rain in Shaanxi during 24Aug. - 7Sept. 2003 and the relationships between the jet streams and the persistent rainstorm. The results show that there is advantageous configuration between the upper jet stream , the South Asia high and the low-level south wind or the low-level jet stream that is important mechanism for the secondary circulation maintaining ,convection continuing and rebuilding.
