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。  相似文献   

The Impact of Air-Sea Interactions on Typhoon Structure   总被引：1，自引：1，他引：0

In this work,the results of a coupled experiment and an uncoupled experiment conducted in one of our former works are used to analyze the impact of air-sea interactions on the structure of typhoons.Results reveal that typhoon-induced SST decreases to reduce the latent heat fluxes transporting from the ocean to the atmosphere and cause the flux of sensible heat to transfer downward from the atmosphere to the ocean.Such SST reduction also has remarkable impacts on the typhoon structure by making the typhoon more axisymmetric,especially in the middle and high levels.This study also analyzes the basic characteristics of symmetric typhoon structure.  相似文献
