Abstract: In this study, 90 typhoon processes occurred in the western Pacific during 2008－2018 were simulated using the COAWST (coupled ocean-atmosphere-wave sediment transport modeling system) model. Based on these simulations and combined with Argo observations, a composite analysis method was utilized to statistically examine the response characteristics of ocean water temperature to typhoon transit. The research found that when a typhoon passed through, the response of sea surface temperature (SST) was delayed. And, in space, temperature change above the subsurface layer exhibited a right bias, while the temperature change below the subsurface layer exhibited a middle bias, indicating that the path center anomaly was greater than the two sides. The average SST anomalies caused by typhoon transit was 0.5 ℃～1 ℃, with a maximum value of up to 2 ℃, which was located at about 50～150 km to the right of the path. Vertically, the water temperature anomaly response in the core of typhoon path was negative. Furthermore, the response on the left and right sides of the path showed a three-layer structure, with temperatures in the 0～50 m shallow layer being negative anomalies; in the 50～125 m subsurface layer being positive anomalies; in the layer below 125 m being negative anomalies. In the area deeper than 300 m, the wind-induced cooling effect decreased up to 0 ℃ as the distance from the path center increased. The “heat pump” effect of typhoon was the primary cause of the temperature increase of the subsurface layer water on both sides of typhoon path, while the “cold suction” inhibited the further cooling of the subsurface layer water.
