基于2005年胶南近岸海域海流的周日连续观测资料,对该海域观测日期内的海流特征、潮流性质及余流特点进行了初步分析;进而在实测资料分析的基础上,利用分步杂交法对潮流场进行了数值模拟计算,展现了M2分潮的潮波系统、潮流椭圆分布、最大流速分布及逐时潮流场。数值计算结果与实测资料分析结果相一致,较好地反映出该海域M2分潮潮流场时空分布的基本特征,对该海域的水动力状况有了更进一步了解,为胶南近岸海域的环境保护规划的制定提供了一定条件下的科学依据。
Based on the continuous observation data of the sea currents in Jiaonan coastal area in 2005, the characteristics of ocean currents, tidal currents and overcurrent during the observation period were preliminary analyzed. Based on the observed data, The tidal current field is numerically simulated and the tidal wave system, the tidal current elliptical distribution, the maximum velocity distribution and the tidal current field are shown. The numerical results are in good agreement with the measured data, which can well reflect the basic characteristics of temporal and spatial distribution of the M2 tide flow field in this area, and have a better understanding of the hydrodynamic conditions in the area. Planning provides a scientific basis for certain conditions.
