烟墩角海域二测站周日水温及潮流变化特征
One-day current and temperature variations at two anchored stations near Yandunjiao
摘要
Abstract
We analyzed water characteristics based on water temperatures and tidal current at Yandunjiao. To col- lect these data, we observed the surface and bottom water layers for 25 hours. Using the tidal current quasi-harmonic method for short term data, we calculated the harmonic coefficients of O1, K1, M2, S2, M4 and MS4 tidal current constituents in north and east components, along with the tidal current elliptic factors. The sea water showed stratification with two fluctuations, which was closely related with the N-S tidal currents. The tidal current in the studied area was classified as regular semidiurnal current, except the surface layer in the Yandunjiao Bay. The north component of semidiurnal current was generally stronger than the east one from our result. The semidi- urnal current was reversing current in our observed area with the N-S direction. The ratio of shallow water tidal current constituent to observed current in surface layer was greater than that of the bottom one.关键词
