基于地波雷达观测资料的烂沙洋海域表层海流特征研究
Surface current characteristics analyzed by HF Surface Wave Radar data in Lanshayang sea area
摘要
Abstract
This paper analyses the characteristics of sea surface currents and residual currents in coastal area of Rudong County,in JiangSu Province,using long-term ocean observation data obtained by HF Surface Wave Radar.Results show that,the sea surface current direction is generally NW-SE.The maximum monthly flow is between 125～ 150 cm/s so that tidal energy is strong here.The average flood current velocity is between 39～63 cm/s and the average ebb current velocity is between 37～64 cm/s.The surface tide is regular semidiumal and M2 is the most important constituent.The tidal current velocity in east-west is 114cm/s,which exceeds the tidal current velocity value of 62cm/s in north-south.The direction of residual current is west-south,and the direction frequency distribution of hourly residual current shows that southward is the largest,followed by southwestward.关键词
