Abstract

Impact of sea-level change on coastal areas has long been a concern of the world, especially the coastal countries. It is an important part in the research of the marine environment. Sea-level change is caused by various social and environmental reasons, among which the contribution of the Antarctic ice caps mass change is a significant factor. In order to investigate the correlation between sea-level change of Chinese coastal areas and the Antarctic ice caps mass change, several geo-statistical methods were involved in this paper. The Antarctic equivalent water height and sea level anomaly datasets were applied. First, the periods of the two datasets above-mentioned are found though the spectrum analysis and a further analysis of these periods is made. Then the correlation analysis is carried out using the time series which span from January 2004 to March 2010. Through the rapid inverse Fourier transform we obtained the cross-correlation function, drew cross-correlation function diagram and analyzed correlation degree and the lag time of these two time series. Research shows that (1) the sea level change has a year cycle as the leading period, meanwhile equivalent water height change has a half year cycle as the leading factor and display a complicated multi-scale coupling fluctuation characteristic; (2) The cross-correlation function diagram indicates that these two time series highly positive correlated when the lag time is 8 month and highly negative correlated when the lag time is 26 month. There is a teleconnection between these two events.
