The three-dimensional structure of the Tropical Cyclone's baroclinic wake is synthesized as an averaged baroclinic-dominant response of the upper ocean. The resulting persisting sea surface depression can easily be monitored using the present-day altimeter constellation. Following a semi-empirical framework, these baroclinic wake signatures are linked to the inner core TC dynamic and the ocean stratification. To collect these fine-scale parameters, spaceborne SAR instruments and Argo fleet are used, to precisely capture the maximum wind region and the irregularities of the ocean vertical structure. This combination of high-resolution information is found paramount to fully capture the modulation of sea surface height anomalies, and its mean trend, especially for major hurricanes. Baroclinic signatures mostly range around 10–20 cm and peak at 40 cm. Deeper anomalies correspond to barotropic response, removed from the present analysis.

全面了解热带气旋下的海气相互作用：论高分辨率和多模式观测的重要性


热带气旋斜压尾流的三维结构被合成为上层海洋的平均斜压主导响应。使用当今的高度计星座可以轻松监测由此产生的持续海面凹陷。按照半经验框架，这些斜压尾流特征与内核 TC 动态和海洋分层有关。为了收集这些精细参数，星载SAR仪器和Argo舰队被用来精确捕获最大风区和海洋垂直结构的不规则性。人们发现，这种高分辨率信息的组合对于充分捕获海面高度异常的调制及其平均趋势至关重要，特别是对于大型飓风而言。斜压特征大多在 10-20 厘米左右，峰值在 40 厘米处。更深层次的异常对应于正压反应，从当前的分析中删除。
