2014年9月，台风卡尔梅吉掠过了南中国海北部的一系列浮标和系泊设备，留下了一组罕见的关于台风引发的上层海洋动力和温盐反应的观测结果。动力响应表现为地面混合层和温跃层中相位相反的强近惯性流，表明响应以第一斜压模的激发为主。除了近惯性振荡外，温盐响应还显示出平均场的相当大的变化。尤其是温、盐度异常一般表现为三层垂直结构，表层变冷变咸，次表层变暖变新，下层又变冷变咸。台风路径右侧表层和次表层的响应较强，而路径沿线和路径左侧的低层响应较强。三维数值模式很大程度上再现了上层海洋响应的这些特征。基于模式的热量收支分析表明，垂直混合是造成地表冷却和次表层变暖的主要原因，而上升流是自下而上冷却的原因。观测和模式结果都表明，台风卡尔梅吉过后，整个上层海洋经历了一次全面的降温。
Typhoon Kalmaegi passed over an array of buoys and moorings in the northern South China Sea in September 2014, leaving a rare set of observations on typhoon-induced dynamical and thermohaline responses in the upper ocean. The dynamical response was characterized by strong near-inertial currents with opposite phases in the surface mixed layer and in the thermocline, indicating the dominance of the response by the excitation of the first baroclinic mode. The thermohaline response showed considerable changes in the mean fields in addition to a near-inertial oscillation. In particular, temperature and salinity anomalies generally exhibited a three-layer vertical structure, with the surface layer becoming cooler and saltier, the subsurface layer warmer and fresher, and the lower layer cooler and saltier again. The response in the surface and subsurface layers was much stronger to the right of the typhoon track, while that in the lower layer was stronger along the track and to the left. These features of the upper ocean response were grossly reproduced by a three-dimensional numerical model. A model-based heat budget analysis suggests that vertical mixing was mainly responsible for the surface cooling and subsurface warming, while upwelling was the cause of cooling from below. Both observations and model results indicate that the whole upper ocean experienced an overall cooling in the wake of typhoon Kalmaegi.
