越南沿海若干验潮站长期观测资料的潮汐分析
Tidal Analysis of Long-term Observation Data of Tide Gauges Along Vietnam Coast
摘要
Abstract
In order to better understand the tidal characteristics and changes along the coast of Vietnam,the harmonic tidal analysis of the long-term observation data at six tide gauge sites of HONDAU,HONNGU,DANANG,QUYNHON,VUNGTAU and RACHGIA is performed to calculate the harmonic constants of the main principle constituents of O1 、P1、K1 、Q1 、M2 、S2 、N2 、K2 and long period tides,such as nodal tide Mn.The results show that the characteristics of the tide along coastline of Vietnam are complex,and the coastal zone is more vulnerable at the time when the seasonal sea level is at its highest.The observed amplitudes of the 18.6-year nodal tide Mn along Vietnam coast are uneven in spatial distribution,and significantly exceed the theoretical amplitudes,by less than 1 cm,which is relative to the changes of the non-tidal low-frequency sea level.关键词
