Abstract
Based on the hourly tidal observations data at the Xiapu Dongchong station,Ningde Cheng'ao station and Fu'an Baima station from 2012 May to 2013 April,tidal characteristics in the Sansha Bay of Fujian were analyzed by means of statistics of each station. The results showed that the tidal type in the Sansha Bay was regular semidiurnal tide,tidal cycle in the Sansha Bay was 12 h 24 min,and the tide was seasonal obviously. The tidal diurnal inequality was evident,diurnal inequality was more obvious during low tide than that during high tide. The Sansha Bay was a strong tide area,the maximum tidal range,average tidal range and minimum tidal range from the mouth to the top along the bay were gradually enhanced,the average tidal range was more than 500 cm,and the monthly maximum tidal range appeared in September,the smallest range appeared in March.
