| 摘 要： | 本文对远距离台风暴雨的发生与非纬向高空急流进行统计分析。结果表明:远距离台风中尺度暴雨与非纬向高空急流密切相关,暴雨发生时,200hPa一般为西南急流,暴雨区位于急流右后方。暴雨增幅时,200hPa高空急流有增强转竖的趋势。

| Abstract: | In this paper, correlation statistics and analysis between the storm rainfall far from typhoon and non-zonal high level jet streak(NHJ)were carried out.The results show that: The NHJ is most closely associated with the storm rainfall far from typhoon. The high level jet(HJ) in 200hPa is constantly southwesterly(90.2 percent) during the period of which storm rainfall occurs . While storm is being intensive ,the HJ has a trend that non-zonal features become stronger. |
