The study explores changes in key oceanographic parameters during the passage of Super Typhoon Mindulle (No. 202116) whose trajectory traversed the Kuril-Kamchatka trench. Analysis utilized GLORYS12V1 (Global Ocean Physics Reanalysis) oceanographic reanalysis data supplemented by satellite imagery and ERA5 (ECMWF Reanalysis 5th Generation) atmospheric reanalysis. Maximum ocean current speeds (>2 m/s) were observed at the typhoon’s southeastern periphery, shifting eastward as the typhoon moved northeast, which indicated its sustained and expanding influence. The most intense upwelling, driven by Ekman pumping, occurred at the western periphery due to wind field asymmetry, weakening as the cyclone progressed. Temperature anomalies were predominantly negative south of the cyclone’s center, with limited areas of positive anomalies at the northern periphery. Salinity anomalies exhibited a more complex pattern with alternating zones of positive and negative values. Comparison of hourly and daily-averaged anomalies confirmed significant ocean cooling behind the typhoon’s path, with dynamic changes more pronounced than thermohaline changes. Within the cyclone’s center, changes in current speeds and thermohaline properties were minimal compared to the periphery, both at the surface and in vertical slices. The results confirm the effectiveness of using GLORS12V1 data to investigate short-term typhoon-induced oceanic processes.
