摘要
台风“天鸽”与“帕卡”影响我国时间间隔紧凑，登陆地点相近，移动路径相似。对这两个台风登陆前出现的强对流天气、台风强度变化、过程降水、大风和物理量场进行对比，发现两个台风均出现台前飑线。“天鸽”影响时间长，风速大；“帕卡”累积降雨量大。除了因为台风本身强度的差别以外，西南急流和季风云系也起到重要作用。物理量场均有利于降水。
When Typhoon ＂Dove＂ and ＂Parker＂ affected China, there was a short time interval, besides, their landing site and moving paths both were similar. We compared the strong convective weather before the two typhoons landing, typhoon intensity changes, process precipitation, gale, and physical quantity field and found that both the two typhoons appeared pre-hurricane squall lines. ＂Dove＂ lasted a longer time and its wind speed was high while ＂Parker＂ accumulative rainfall was higher. In addition to the difference in the intensity of the typhoons, the southwest jet and the cloud system of monsoon also played an important role and the physical quantity field was beneficial to the precinitation.
