| 摘 要： | 利用前期工作中耦合试验和未耦合试验对台风Krovanh(2003年)数值模拟的结果,分析了海-气相互作用对台风结构的影响。结果表明,台风引起的海面降温大大降低了海洋向大气输送的潜热通量,同时使得感热通量向下传递到海洋。另一方面,台风引起的海表面温度(SST)降低,反馈到台风使其结构轴不对称性加强,且在中高层尤为显著。分析了台风对称结构的基本特征。

| Abstract: | The results of a coupled experiment and an uncoupled experiment conducted in one of our former works are analyzed to explore the impact of air-sea interactions on typhoon structure. Analysis reveals that the typhoon-induced SST cooling reduces the latent heat fluxes directing from the ocean to the vortex. Moreover, the fluxes of sensible heat are from the vortex to the ocean. SST cooling also has remarkable impacts on typhoon structure by lowering the symmetric index and making the typhoon more asymmetric, which is more pronounced in the middle and high levels. This study also analyses the basic characteristics of symmetric typhoon structure. |
