摘要

The temporal and spatial variabilities of the mesoscale oceanographic features in the East China Sea are studied by satellite remote sensing data. The remote sensing data used in this study are sea surface temperature (SST) data from NOAA/AHRR ocean color data including chlorophyll a from Orbview-2/SeaWiFS, Terra/MODIS, and Korean Multi-Purpose Satellite/OSMI (Ocean Scanning Multi-Spectral Imager). The major oceanographic features studied in this paper as follows. We studied how to detect low salinity water from the Yangtze River, that gives damages to the Korean fisheries. MODIS data were used to explain the front of the high concentration suspended solid on the shelf in the East China Sea. The horizontal distribution of the resuspended solid was depended on the wind force, tidal current and stratification of water. The horizontal distribution area of the resuspended solid in winter season during January-April were three times wider than those in summer season during June-September. The mesoscale cold core eddies formed in diameter of 150km had occurred in the East China Sea in February and May. The mechanism of eddy formation was studied by each condition, including boundary condition between the East China coastal cold water and the Kuroshio warm current, wind data related to the monsoon which was measured QuikScat, and the bottom topography of the East China Sea. Abnormal oceanic conditions associated with the passage of typhoons are examined using hydrographic and satellite data. An abrupt decrease of SST in range of 3 to 5℃was observed.
