| Abstract: | The sea surface temperature (SST) data from AVHRR during 1985-2005 were applied to analyze the variability in East China Sea (ECS) and the warming trend is found in general. The Empirical Orthogonal Function (EOF) and Spectrum analysis were used to analyze the variability of SST anormality (SSTA). The first model (EOF1) explains 34.8% of the total variation and its main period is 3~5 a. It shows that there is a warming trend in most area and the largest variation appear in the inshore area.The period of EOF2 (10.7%) is 2 a and it denotes the change of SSTA in south-east area is opposite to that of north-west.The variation range of SSTA in Taiwan Strait and the south in ECS are similar, while that of the north is much stronger.They all contain the period of 5~7 a, same as that of ENSO.The SSTA in 3 area are affected strongly by ENSO and the 2a delay is obvious.There are 8~9 and 16~18 month delay between the south of ECS and ENSO. It mainly due to the anomalous Kuroshio transport. The SSTA of the north shows a close correlation with the variation of air temperature there and the correlation up to 0.92. |
