摘要
通过对 1999年秋季一次突发性降水过程高空急流的分析 ,发现急流入口区南侧辐散 ,其低层辐合上升 ,当低层有印缅槽活动的时候 ,对流加强 ,印缅槽发展 ;急流入口区北侧辐合 ,其低层辐散下沉 。
The analysis of the upper level jet stream occurred in a sporadic intensive precipitation process in winter of 1999 found that divergence occurred at the south side of jet stream inlet and its lower level convergence rose. When the Indo Burma trough is active in low level, convection strengthens and Indo Burma trough develops; convergence occurs at the north side of jet stream inlet and its low level divergence goes down, and southward non geostrophic occurs.
