Empirical Orthogonal Function Analysis Of Avhrr Sea Surface Temperature Patterns In Taiwan Strait, Ming-An Lee, Ching-Dong Yeah, Chao-Hsiung Cheng, Jui-Wen Chan, Kuo-Tien Lee

Journal of Marine Science and Technology

Empirical orthogonal function (EOF) analysis was used to study a time-series of the Advanced Very High Resolution Radiometer (AVHRR) imageries from the waters of Taiwan Strait to examine the temporal and spatial characteristics and to determine the dominant pattern of sea surface temperature (SST) variability for 72 months from January 1996 to December 2001. The spatial variance was consistent with a quasi-permanent front at the Chang-Yuen Ridge in winter and associated with strong temperature contrast to the Kuroshio branch or the South China Sea Warm Current. It also displayed a cool water plume extending from the Peng-Hu Islands to Formosa …
