利用多平台卫星和Argo浮标观测资料，系统研究了2012年超强台风Tembin（Tembin）在西北太平洋的上层海洋响应，特别是台风与前期冷心涡（CCE）的相互作用，发现台风过后沿着路径出现了显著的海表温度（SST）冷却和海表高度距平（SSHA）减小，最大SST冷却和SSHA降低分别达到4.0°C和25 cm。先前存在的CCE位于台风路径的左侧，导致SST冷却的有趣的偏置。最大SST冷却出现在台风路径左侧约25 km处，路径左侧SST冷却比右侧大40-100%。台风过后，由于台风的气旋性风应力，CCE扩大了50%。温跃层被台风引起的上升流抬升了15-25 m。基于Gregg-Henyey-Polzin参数化方法，从高分辨率Argo浮标资料中推断出台风增强的垂直混合。台风后的透圈扩散系数达到9 × 10−4 m2 s−1，比台风前大10倍以上。
ABSTRACT Using multiplatform satellites and in situ Argo float observations, this study systematically examined the upper ocean response to Super Typhoon Tembin (2012) in the western north pacific, and the interaction between typhoon and a pre-existing cold core eddy (CCE) was particularly focused on. Significant sea surface temperature (SST) cooling and sea surface height anomaly (SSHA) decrease was detected along track after typhoon, with the maximum SST cooling and SSHA decrease reaching 4.0°C and 25 cm, respectively. The pre-existing CCE was located to the left of the typhoon track, resulting in an intriguing leftward bias of SST cooling. The maximum SST cooling appeared at about 25 km to the left of the typhoon track, with SST cooling to the left of the track 40–100% larger than that to the right. After typhoon, the CCE was expanded by 50% due to the typhoon’s cyclonic wind stress. The thermocline was uplifted by 15–25 m by the typhoon-induced upwelling. Typhoon-enhanced vertical mixing was inferred from high-resolution Argo float data based on the Gregg–Henyey–Polzin parameterization method. The diapycnal diffusivity reached 9 × 10−4 m2 s−1 after typhoon, which was more than 10 times larger than that before typhoon.
