越南中部沿岸潮汐、潮流特征

摘要

: Based on the tide and current data, the characteristics of tide and tidal current along the middle coast of Vietnam have been analyzed. The results showed that; 1) The research area was the tide transitional belt and the tide was mainly the diurnal tide, and 20 d in one month was diurnal tide and 10 d was semidiurnal tide;2) The tidal current was mainly irregular semidiurnal, and then irregular diurnal. It was mainly reciprocating flow;3) The major axis of O1、K1、M2' S2 constituents concentrated in the direction between SW and NE, which was along the coastline;4) Affected by the southwest monsoon, a clockwise residual current flowed from SW to NE at the surface%基于越南中部2007年夏季潮汐、潮流实测资料,对该区域的潮汐、潮流特征进行分析,分析结果表明:1)研究海区为以日潮为主的潮汐过渡地带,每月有20 d属日潮,10 d属半日潮；2)潮流以不正规半日潮流为主,其次为不正规全日潮流,潮流运动以往复流为主；3)O1、K1、M2、S2分潮流长轴方向集中在SW-NE之间,与岸线走向基本一致；4)受西南季风的影响,表层存在一沿岸形自SW向NE运动的顺时针余流场.
