Abstract

Based on 22 sparse-distributed tide gauge records in the Northwest Pacific Ocean marginal sea, the process, characteristic and prediction of regional sea level change are discussed by the integration of 6 mathematic methods. The AA. apply first the regularized EM algorithm (RegEM) and the Multi-taper Spectral Method (MTM) to investigate the fluctuation characteristics, processes and their spatial heterogeneity from temporal and frequency pespectives. They further use ordered cluster methods to get 5 sub-regions. They use Mean Generation Function (MGF) to predict sea-level change of each station until 2030. Finally, the Principal Component Analysis (PCA) is employed to obtain regional-scale sea level change trends, sea level rise rates of these 5 sub-regions from 2001 to 2030. Chinese coast along the Yellow Sea and East China have the largest rise rates. The rate changes near the coast of Japan are a little smaller. Sea level changes along northwest of South China Sea and north of the Yellow Sea and Bohai Sea are much smaller
