Kuroshio front and oceanic phenomena near Taiwan and in the Southern Okhotsk sea from ERS SAR data

摘要: Surface manifestations of the Kuroshio current system and diversitied oceanic phenomena were studied by analysis about 400 ERS-I SAR irnages two test areas (20-28°N, 118-124°E 43-48°N, 142-150°E) located in different climatic zones. Weather maps, NOAA AVHRR ARGOS buoy data used to interpret signatures. Of particular interest strips images which covered same east Taiwan Southern Okhotsk Sea. The increased values NRCS (bright bands) due short gravity-wave/current interaction along shear and/or convergence zones within front. reduced (dark concentration slicks aligned frontal boundaries. Eddy-like wave-like disturbances caused its branches with ambient seas, underwater mountains, islands. Spiral mushroom-like eddies packets internal waves observed south, northeast
