利用基于数学形态学的多尺度、多结构元素、自适应加权的边缘检测技术,对2002年9月至2008年8月共6年的海表温度(SST)卫星遥感数据进行分析,得出台湾海峡及其周边海域上的主要锋面位置及其季节、月变化规律.检测结果表明,在研究海区共存在4个比较稳定的海表温度锋:台湾浅滩锋、浙闽沿岸锋、彰云海脊锋和东海陆坡黑潮锋.锋面强度及范围呈冬强夏弱的特点.1～5月份往往是锋面的活跃期,7～10月份普遍为锋面消亡期.
Based on the multi-scale and multi-structure elements based on mathematical morphology and adaptive weighted edge detection, the SST satellite remote sensing data from September 2002 to August 2008 for a total of 6 years were analyzed. Stratigraphy and its surrounding waters, and its seasonal and monthly variation.Results show that there are four relatively stable sea surface temperature fronts in the study area: Taiwan’s Former Shore Front, Zhejiang-Fujian Coastal Frontier, Changyun Sea Ridge And the front of the Kuroshio front of the East China Sea on the slope. The frontal intensity and range are characterized by the weak winter and the weak summer. From January to May, they are often the active phases of the frontal phase, and generally disappear from July to October.
