黄河入海物质输运通道

摘要
渤海水体浊度的分布及其季节变化反映了悬浮物质的分布、输运及其季节特征。本文利用2012—2016年渤黄海8个航次现场观测的水体温度、浊度数据,并结合CCMP(Cross—CalibratedMulti—Platform)风场数据、ROMS(RegionalOceanModelSystem)海流数值模拟结果,分析了渤海海域水体浊度季节分布特征。水体浊度的大小与风速的季节变化密切相关,冬季,黄河口及附近海域的浊度值最高,离岸31km到56km处浊度值从180NTU迅速下降至54.3NTU,而其他季节的浊度较低;渤海全年20m以深海域再悬浮较弱,以水平扩展为主。进而甄别了黄河口附近高浊度水体向渤黄海输运的两条路径,分别为:冬夏季均存在的沿渤中浅滩西侧通道向渤海北部扩展和冬季存在的沿莱州湾湾口向渤海海峡南部及北黄海输运,该两条路径主要由环流场控制。
The distribution and seasonal variation of turbidity in Bohai sea water that reflects the characteristics of suspended sediment which distributed,delivered and seasonal changes.By using temperature and turbidity data of water in the Bohai sea from eight cruises in 2012 to 2016,and combined with CCMP wind field data,the ROMS current numerical simulation results,that analyzes seasonal distributed characteristics of turbidity in Bohai sea.The turbidity is closely related to the wind speed.In winter,the turbidity of the Yellow River estuary and the nearby sea area is the highest,and the turbidity drops rapidly from 180 NTU to 54.3 NTU in the 31 km to 56 km offshore.However,the turbidity is low in other seasons.During the whole year,no resuspension occurred at the depth of 20 m,mainly horizontal expansion.During the whole year,no resuspension occurred at the depth of 20 m,mainly horizontal expansion.
