在这项研究中，我们利用三个漂流浮标的数据、高分辨率的全球温、盐度剖面数据和卫星数据，研究了2012年台风Tembin对上层海洋的响应。结果表明，在距台风中心50 km处，近地表气流速度为2.3m·S·1，而在其他类似台风个例中，气流速度往往小于1m·S·1，远弱于台风Tembin。究其原因，是漂流浮标在冷暖水团交汇处锋面区域遇到了较大的流量变异性。因此，在其他类似的台风过程中，平均风速较小。超强台风过后1~2d左右路径有较强的垂直混合，使左、右路径温度降低、盐度升高，强台风过后5~6d左右路径有较强的垂直混合，使左右路径温度降低、盐度升高。混合层下方有明显的上升流。
In this study, we explore the upper-ocean responses to Typhoon Tembin in 2012 with three drifting buoys' data, high-resolution global temperature and salinity profile data, and satellite data. Results show that in the 50 km from the typhoon's center, there was a near-surface flow velocity of 2.3 m?s?1. In other similar typhoon cases, however, flow velocity was often less than 1 m?s?1, much weaker than Typhoon Tembin. The reason is the drifting buoy in the frontal area of the intersection of cold and warm water masses encountered large variability of flow. So, the average flow velocity was small in other similar typhoon cases. There was strong vertical mixing, making temperature decreased and salinity increased at both left track and right track 1~2 days after the super strong typhoon passed by, and at the right track 5~6 days after the strong typhoon passed by. There was obvious upwelling below the mixed layer.
