Analysis of Characteristics of Tide and Tidal Current in the east China Seas

Abstract The features of tide and tidal current in the east China seas were studied by FES2014 data gauge station data. It is found that well agreement with observation. Among four major components (M2, S2, K1, O1), M2 strongest component maximum amplitude (tidal current) exceeds 100 cm (100 cm/s), followed S2 its reaches 60 (50 cm/s). results indicate are dominated semi-diurnal tides. There amphidromic points for tides, two diurnal Rotating dominates areas far from coast, rectilinear coastal sea area. strong currents often distributed some places special topography such as bays estuaries.
