ABSTRACT: In this paper we consider the Zhejiang (ZJ) provincial coastal area to find 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 have been presented and discussed. SL is indicating an increasing trend; however, there is a decreasing trend between the years 1975 and 1987. Over ZJ increase in SL increase is 0.34 mm in SL from 1958 to 1975 and after 1987 there is 0.24 mm increase, overall increase is 0.17 mm from 1958 to 2015; however, decrease in SL 0.26 mm from 1975 to 1987. Maximum SL observed in 2012. Negative relation between SL and Sea surface temperature (SST) found over ZJ province.
