【摘要】 通过诊断“04、05”号热带风暴登陆后减弱成台风低压的变化特征,分析其路径相似却出现降水实况不同的成因,结果表明:台风低压暴雨主要决定于登陆后台风低压的移动路径和高低层结构维持时间的长短,稳定的湿舌、“湿锋”、台风低压辐合线的持续加强、急流的北推西进以及有利地形都可使降水得到明显增幅。更多还原

【Abstract】 The characteristics and causes of two landfall typhoon lows No.0604 and No.0605 which bring different precipitation on the similar track are analyzed.Results show that it plays an important role to the heavy rainfall that the track of the landfall typhoon low and the systems on the upper and the lower levels maintaining long.The stable moisture and moisture front,strength of the convergence line,low level jet moving to the north and west and the topography are all the factors to enhance the heavy rain.更多还原
