基于形态学的边缘检测方法已用于研究台湾海峡及其邻近地区的海面温度（SST）锋面。该方法基于具有多维和多结构元素的数学形态学。利用2002年9月至2008年8月六年的海温数据，我们区分了黑潮锋面等大型海温锋面和较小的海温锋面，即台湾岸锋面、哲民海岸锋面和章云岭锋面。还研究了这些锋面的季节性和每月变化。一般来说，海温锋冬季较强，夏季较弱。 1-5月为锋面活跃期，7-10月为锋面衰退期。
A morphology-based edge detection method has been used to study sea surface temperature (SST) fronts in the Taiwan Strait and its adjacent area. The method is based on mathematical morphology with multi-dimensional and multi-structural elements. Using six years’ SST data from September 2002 to August 2008, we distinguished the large SST front like Kuroshio Front as well as the smaller ones: namely Taiwan Bank Front, Zhe-Min Coastal Front and Zhang-Yun Ridge Front. The seasonal and monthly variations of these fronts were also studied. Generally, the SST fronts are stronger in winter but weaker in summer. And the fronts are at their active stage during the period from January to May but at their declining stage during the period from July to October.
