摘　　要：0917号超强台风是2009年在西北太平洋地区生成的生命期最长、登陆次数最多、移动路径最为怪异的超强台风。本文利用多种资料,分析了"芭玛"强度及移动路径特点,并对引起其移动路径及强度异常变化的原因进行了初步分析,结果表明:(1)9月底至10月中旬,副高发生了一次"加强西进-减弱东撤-加强西进"的周期性活动,对台风移动路径变化起着重要作用;(2)"芭玛"和"茉莉"产生的双台风效应是造成"芭玛"向东南方向转向的主要原因;(3)西风槽东移、水汽和能量输送的变化、下垫面的改变以及冷空气的影响使"芭玛"强度多次发生变化。Super typhoon＂ Parma＂（0917） is the typhoon with the longest life cycle and the most number of landings generated in the Northwestern Pacific.Its moving track is anomalous.Using multiple data,the character-istics of intensity and moving track of Typhoon Parma,as well as the respective cause,were analyzed.The results showed that,（1） from late September to mid-October,subtropical high strengthened and moved westwards,then weakened and moved eastwards,and then strengthened and moved westwards again,which had important effect on the change of the moving track of typhoon;（2） the Fujiwhara effect of binary cyclone between typhoon＂Par-ma＂and typhoon＂Melor＂was the main reason for typhoon＂Parma＂turning to the southeast;（3） the east moving of westerly trough,the variation of the moisture and energy transportation,the friction of underlying surface,the Fujiwhara effect of binary cyclone and the cold air also contributed to several intensity variations of typhoon ＂Parma.＂
