摘要
Trajectory diagnostic methods were used to analyze air parcels of high- and low-level jets during the heavy rainfallof 4-6 July 1991.It is found that air parcels above rainfall area travelled from the entrance of the high-level jet,passingthrough the jet center and reached the exit region.Upper tropospheric divergence over rainfall area resulted fromdecelerative motion of the jet flow.Warm and moist southwest flow converged and ascended ahead of the low-level jet.The decreasing of low-level pressure as a result of high-level divergence that caused the low-level jet becameunexpectedly strong.
