Short summary

Based on multiple datasets, we investigate the influence of two anticyclonic eddies on upper-ocean responses to Typhoon Kalmaegi in the northern South China Sea. This nuanced response is intricately linked to factors including the relative position of the eddies and the TCs, the eddies' intensity, and the background current. This work will further improve the accuracy of TC forecasts and enhance the simulation capabilities of air–sea coupled models.
