| 摘 要： | 0814强台风"HAGUPIT"和9615台风"SALLY"具有移速快、强度强、路径相似的特点,通过分析得出,500 hPa不断加强的大陆副热带高压,南侧偏东引导气流加强,使热带气旋移速不断加快,而且与热带气旋同向移动增强的副热带高压,使其移速更快。越赤道气流增强和维持,给热带气旋不断输送能量,对流层高层强辐散,弱纬向风垂直切变都有利于热带气旋显著加强和维持。

| Abstract: | The characteristics of fast movement,strong intensity and similar track from severe typhoon Hagupit and Sally are analyzed.The conclusions are reached that： tropical cyclone accelerates because of the continuous strengthening of the easterly steering airstream on the south edge of the subtropical high.Moreover,the intensifying subtropical high extending towards the same direction with tropical cyclone also contributes to its fast movement.And the strong and persistent cross-equator flow,sustaining upper-level divergence and weak vertical wind shear favor the strengthening and maintenance of tropical cyclone. |

| Keywords: | synoptic meteorology subtropical high strong-wind area cross-equator flow weak vertical wind shear tropical cyclone |
