强台风“菲特”的移动路径及强度分析

对强台风“菲特”进行高低层形势场分析，对其移动路径的预报和台风强度问题进行了初步探讨．分析发现，“菲特”主要受中低层引导气流的影响.利用日本静止卫星MTSAT的反演产品分析了“菲特”的强度变化情况，得到“菲特”在登陆后垂直风切变在10~15 m·s^-1，不利于其强度的维持或发展．

Analysis on the moving track and intensity of severe typhoon “Fitow”

We have analyzed the situation of high and low levels of the severe typhoon “Fitow”. A preliminary study on the prediction of the track and intensity of the typhoon are discussed. Through analysis, we find that “Fitow” is mainly affected by the low level steering flow. Derived products of Japanese geostationary satellite MTSAT is used to analyze the intensity change of “Fitow”. In addition, the vertical wind shear is between 10 and 15 m·s-1 after “Fitow” landing, and is detrimental to its strength to maintain or develop.
