台风是最强的暴雨天气系统,针对台风暴雨的研究由来已久,并把台风暴雨分为台风环流本身的暴雨和台风远距离暴雨。近几十年来,有关台风远距离暴雨的研究有了一些新的进展和成果。2007年的第十四届全国热带气旋研讨会上还给出了最新的台风远距离暴雨定义。谨从此定义出发,简要总结国内外在台风远距离暴雨方面的研究成果,并在分析归纳的基础上提出存在的问题和可能的研究方向。
Aa a weather system that causes severe rainfall,tropical cyclones(TCs) have been studied for a long time by meteorologists.Besides their own rainfall,remote rainfall is also related to TCs,which is caused by interactions between TCs and mid-latitude weather systems,such as troughs,southwest vortexes,northwest vortexes,and northeast vortexes,etc.Observations and studies show that the interactions played an important role in the occurrence of TC remote rainfall.In those events,TCs-related low-level jet streams transport abundant moisture and energy into mid-latitudes and converge there.Meanwhile,mid-latitude weather systems provide large-scale background for the occurrence of TC remote rainfall.
