FEATURES OF THE HYDROLOGICAL REGIME OF THE KUROSHIO CURRENT DURING THE FORMATION AND DEVELOPMENT OF THE LARGE MEANDER LM2017

Abstract

The study investigates the spatio-temporal variability of the Kuroshio Current based on satellite data of sea surface height (SSH) and geostrophic velocities, as well as in situ expeditionary measurements (temperature and salinity of seawater) provided by the National Oceanic and Atmospheric Administration (NOAA). Along various sections in the region of the Kuroshio Current, maps of the spatial distribution of current velocities were constructed and volume transports were calculated. A double-core structure of the current was identified, which may be associated with meandering of the main flow and the influence of bottom topography. It is shown that the Kuroshio is characterized by the persistent existence of meanders whose geographical position remains relatively stable over time, while their configuration is variable. The obtained results are consistent with satellite observations and can be used for further studies of ocean circulation and applied tasks, particularly in the field of marine navigation
