摘　　要：对2011年国庆前后相继登陆于海南的2个热带气旋"纳沙"和"尼格",从两者的形势场、环流结构特征以及通过对相关物理量场特征来进行分析,结果表明,副热带高压是"纳沙"、"尼格"最直接的影响和控制因素,北方冷空气是影响其强度、移动路径的又一重要原因;并对比两者的大气环流形势、卫星云图、涡度、水汽通量、θse场等物理量,找出造成相近、相似路径的热带气旋登陆点以及登陆强度不一样的原因。The tropical cyclones Neast and Nalgae that landed in Hainan Province in the 2011 National Day were compared and discussed through synoptic situation field,structural characteristics of general circulation and other related physical quantities. The results showed that the subtropical high is the most direct effective and control factor of the typhoon Neast and Nalgae,and the cold air from the north is another important reason that changed their intensity and movement path. In order to find the reasons why the landing and landing intensity of the tropical cyclones with similar path aren＇t the same,their atmospheric circulation situation,satellite images,vorticity,water vapor flux,θse field and other physical quantities were compared.
