2007年长江口邻近海域夏季上升流演变机制研究
Mechanism of upwelling evolvement in the Yangtze River Estuary adjacent waters in summer, 2007
摘要
Abstract
We utilized the high resolution satellite product, NGSST sea surface temperature (SST) and cross cali-brated multi-platform (CCMP) wind data, the empirical orthogonal function (EOF) method and numerical ocean model (ROMS) to investigate the evolution of upwelling and its influence on SST anomaly in this specific region. The result indicated that the intensity and spatial distribution of upwelling in summer exhibited an evident variation, which was the key factor for the SST anomaly. The effect of the wind field was local and primarily influences its short term evolution, while the contribution of wind stress curl was on a par with the component of wind stress along the coast. The topographic variation determined the center of the upwelling, which could be induced at the strong inflow flank above the steep and narrow heave, and a corresponding downflow occurs behind the heave.关键词
