利用中国气象局整编的CMA-STI热带气旋最佳路径数据集和NCEP/NCAR再分析资料，对2006年超强台风桑美（Saomai）在我国近海的突然增强过程进行诊断分析，结果表明：在Saomai 突然增强过程中，总涡度收支在高层首先开始增加，接着中层涡度开始增加并逐渐向低层伸展，当高层涡度由增大转为减小，中低层涡度都转为增大时，Saomai趋于突然增强。在Saomai突然增强过程中，在对流层中低层，涡度平流项贡献最大，这与同期活动在西太平洋洋面上Saomai 西侧的热带气旋宝霞（Bopha）有密切联系。进而利用中尺度模式WRF＿ARW V 3．3进行数值模拟，结果表明：在Saomai西侧，Bopha的气旋性环流并入Saomai后，Bopha减弱而Saomai突然增强，Bopha残涡（remnant）正涡度带的卷入是Saomai在我国近海突然增强的重要原因。

Using the CMA-STI Best Track Dataset and NCEP/NCAR reanalysis data,super typhoon Saomai(0608) is diagnosed during its rapid intensification stage over the coastal waters of China.The results show that the total vorticity budget begins to increase in the upper troposphere,and then it increases in the mid-level and gradually stretches to the lower troposphere.When the upper vorticity decreases and the middle and lower vorticity both in-crease,Saomai becoms rapid intensification.The vorticity advection term contributes greatest to the rapid-intensifi-cation of Saomai in the mid and lower troposphere,which is closely linked with tropical cyclone Bopha(0609).Fur-ther exploring the advanced research meso-scale model WRF_ARW V 3. 3 to study,the simulation results show that the intensity rapid change over the coastal waters of Saomai is closely related to the entrainment of vorticity belt into its circulation from the remnant of typhoon Bopha (0609)which is neighboring to Saomai.
