Description:Using a 3 ‐D high ‐resolution ocean model, this paper explores the mechanisms that cause surface and subsurface water cooling northeast of Hainan Island during summer. Results show that two cooling centers in the regions east of Wenchang city and east of the Qiongzhou Strait occur when tides areincluded in the model. The cooling is primarily caused by large ‐scale changes in the circulation in the northwestern South China Sea (SCS) through anomalous horizontal pressure gradients caused by inhomogeneous tidal mixing between the near ‐shore and off ‐shore regions. East of Wenchang city, the offshore tidal currents induce upwelling that brings the near ‐bottom cold water to the subsurface. For the region east of the Qiongzhou Strait, the tidally induced westward anomalous currents suppress the warm
