Sea Level Variations at Different Coastal Areas of Zhejiang Province, China

In this paper we consider the different locations of Zhejiang (ZJ) provincial area including Hangzhou Bay (HZB), Ningbo (NB), Zhoushan (ZS), Taizhou (TZ) and Wenzhou (WZ) subareas to find out the sea level (SL) variations. Sea Surface Height Relative to Geoid over these areas has been obtained from the satellite altimetry data produced routinely by the European Centre for Medium-Range Weather Forecasting (ECMWF) and Archiving, Validation and Interpretation of Satellite Oceanographic (AVISO) data. Monthly, seasonal and interannual variations of SL over ZJ provincial areas have been presented and discussed. SL is indicating an increasing trend, however there is a decreasing trend between the years 1975 and 1987, in later years SL increasing. Over Zhejiang provincial areas revealing increasing trend in SL. Negative relation between SL and Sea surface temperature (SST) found over ZJ province areas.
