Abstract

The satellite altimeter data, sea surface temperature (SST) data and on-site sea level data are used to analyse the effects of the ENSO on the sea level in the offshore areas of China, and to investigate the regional characteristics of the effects of ENSO on the sea level in this paper. Results show that significant teleconnection exists between the SST of the tropical Pacific Ocean and the sea level in the China Sea, and the correlation coefficient decreases progressively from south to north. Thus the offshore areas of China can be divided into three regions:the Bohai and Yellow Sea, the East China Sea, and the South China Sea. The correlation in the South China Sea is the most significant, with the coefficient larger than 0.6 at most areas. The correlation coefficient in the East China Sea is smaller than that in the South China Sea but larger than that in the Bohai Sea and Yellow Sea, and in most areas the coefficient is larger than 0.4. The correlation in the Bohai and Yellow Sea is the weakest among the three areas, yet the correlation coefficient is larger than 0.3 and has passed the significant tests. The annual amplitudes of the sea levels at tide gauges along the coast of China are also studied. It reveals that the seasonal variations of the sea levels at tide gauges are significantly correlated with the ENSO and show distinctive regional characteristic. Thus according to the correlations, the coast of China can be separated into three regions, the area in the north of the Changjiang River Estuary, from Changjiang River Estuary to the Taiwan Strait and south of the Taiwan Strait. Furthermore, the results indicate that the annual amplitude of the sea levels is at low level in El Niño years, and the minimal annual amplitude during the whole period occurs in the El Niño year as well. And the response intensity of the annual amplitude of the sea levels to the ENSO is highly related to the intensity of the ENSO events. When the ENSO event is strong, the response region is relatively larger and the amplitude is bigger than normal situations. The sea levels show significant oscillation period scaled at about 4-7 years in the above three sea regions. For the fluctuation with the period of 7 years in the South China Sea, the oscillation amplitude is about 1.5 cm, which is the largest among all frequencies. In the East China Sea the amplitude is about 1.3 cm. The amplitude of the 6 years period in the Bohai Sea and Yellow Sea is the minimum, less than 1 cm.
