 Abstract: The ocean circulation variabilities are represented in numerical experiments with steady external forcings without interannual variability. These variabilities are known as “Ocean Intrinsic Variability”. The intrinsic variability is mainly concentrated on the mid-latitude western boundary currents such as the Kuroshio, Gulf Stream, and Agulhas Current, and their extensions.The East/Japan Sea (hereafter the East Sea) also has various ocean current patterns and eddies, and the upper layer circulation is driven by interactions with various external forcings. The East Sea shows intrinsic variability in numerical experiments. However, previous studies are insufficient on the physical mechanism of intrinsic variability in the East Sea.In this study, the physical mechanisms of intrinsic variability are analyzed using numerical experiments. The experiments are conducted with constant forcings and seasonal variation in the external forcings. The intrinsic variabilities in the East Sea mainly appear in the meandering or eddy-rich activity regions. In the southern part, the sea surface height anomalies propagate westward to the western boundary due to the baroclinic Rossby waves. The Rossby waves can change the strength of the eastward jet or the north-south movement of the jet axis. Among the external forcings, the volume transport through the Korea/Tsushima Strait is an important factor for driving intrinsic variability, and wind stress plays a role in expanding and strengthening variabilities.Acknowledgement: This work was funded by the Korea Meteorological Administration Research and Development Program under Grant KMI2022-01210 and the National Research Foundation of Korea (NRF) grant funded by the Korea government(MSIT) (No. 2021R1A4A1032646).
