The Extension Form and Seasonal Variation of the Changjiang Diluted Water During 2006--2007
Abstract：The extension form and vertical structure of the Changjiang diluted water by the CTD and ADCP data are analyzed in the paper. The results indicate that the surface layer of Changjiang diluted water was limited in the Changjiang mouth, Hangzhou bay and Zhoushan in spring, autumn and winter. The extension of the Changjiang diluted water in summer can be divided into three st-ages, shooting shape flow stage, the Changjiang water ran southeast into the sea; water tongue-like extension stage, diluted water which was located between the south Yellow Sea cold water mass and continental shelf of the East Sea mixed water pointed to the northeast. Its movements were at the mercy of the Taiwan Warm Current and South Yellow Sea cyclonic circulation; diffusion stage, the diluted water first in the way of bulk water block, and then in the way of de- creasing water block following the background flow field. One branch moved northeast to the South Yellow Sea, another branch turned to southeast, moving in the way of cold eddy winding the northeast of the East Sea.
