琼州海峡西南部秋季海流特征分析
Analysis of autumn current characteristics in the southwest of Qiongzhou Strait
摘要
Abstract
In order to understand the characteristics of tidal currentt in the southwest of Qiongzhou Strait,the quasi harmonic analysis method is used to analyze the measured current data in the autumn of 2022.The results show that the southwest of Qiongzhou Strait is dominated by regular diurnal tide,while the nearshore is irregular diurnal tide;The rising tide mainly flows westward,while the falling tide mainly flows eastward;The maximum flow velocity of the tidal current ranges from 0.85 to 2.58 m/s,with directions of west-east and southwest-northeast.The residual flow velocity is between 0.01 m/s and 0.23 m/s,and the residual flow direction in the surveyed sea area is mainly in the west direction.This study enriches the hydrological data of the surveyed area and provides basic data for the development,utilization,and navigation safety of the region.关键词
