摘　　要：我国暴雨天气中 ,台风是最强的暴雨天气系统。当台风外围系统与西风槽相互作用时往往发生暴雨突然增幅现象 ,造成严重灾害。以往大量的研究表明 :台风和中纬度系统相互作用引起的远离台风的北段暴雨大多发生在西南风高空急流区的右后方 ,高空急流有明显的非纬向特征 ,而且暴雨增幅与高空急流的非纬向增强有关。对有关高空急流与中纬度系统影响下台风暴雨的研究进行了综述 。Typhoon is the most intensive synoptic system that can result in heavy rainfall in China. The interaction between the westerly trough and synoptic system far from typhoon constantly leads to abrupt reinforcement of rainfall and severe disaster.The north part heavy rainfall is called as heavy rainfall far from typhoon. Researches show that heavy rainfall far from typhoon mostly occurred at the right side behind the south westerly high Jet that has distinct non zonal features, at the same time, reinforcement of heavy rainfall is closely associated with strength of non zonal features. Researches on heavy rainfall far from typhoon and non zonal high level Jet streak are reviewed.
