Relatively weak hurricane-induced cooling (<1°C) is often observed in the Loop Current, while observed sea surface temperature (SST) cooling is much stronger in the Kuroshio. This was previously attributed to strong advection effects by the Loop Current. Based on a budget analysis, this study quantitatively diagnoses the dynamic and thermal responses of the Kuroshio to typhoon Megi and four additional tropical cyclones (TCs), which produce up to~3°C SST cooling within the Kuroshio itself. The results show that the surface thermal response of the Kuroshio is a wind-induced temperature cooling primarily due to vertical mixing (up to 96%). The dynamic response of the Kuroshio depends not only on TC conditions (intensity and wind direction) but also on prestorm ocean conditions (e.g., ocean mixed layer depth, baroclinicity, and current velocity). Differently from the open ocean where the ocean gains kinetic energy mainly from wind stress work, the Kuroshio can obtain greater kinetic energy from its baroclinic pressure work, especially in the upper ocean. The strong SST cooling observed in the Kuroshio region is therefore likely associated with the kinetic energy extracted from the Kuroshio baroclinic potential energy, which greatly enhances local vertical mixing.
