摘　　要：利用ＳＰＥＣＴＲＵＭ－９０资料和国家气象中心的Ｔ４２Ｌ９格点资料分析了台风Ｙａｎｃｙ（９０１２）打转运动的过程，认为来自台风上游西风带的高频扰动（周期约１天）及其传播过程对台风打转运动可能有重要影响．By using the SPECTRUM-90 data and T42L9 grid data from NationalMeteorological Center,the looping process of Typhoon Yancy is studied.The resuItshows that the westerlies high frequency fluctuation(with a period of about one day)and the propagating process would exert important influence on the looping track ofTyphoon Yancy.
