渤中浅滩对渤海夏季底层冷水带的影响
Influence of the Central Bohai Shoal on the Bottom Cold Water Belt in Summer
摘要
Abstract
Based on the Finite Volume Coastal Ocean Model(FVCOM),this paper simulated the three-dimensional structure of the temperature field in the Bohai Sea in the summer of 2016,and accu-rately described the temperature distribution characteristics of the bottom layer of the Bohai Sea in sum-mer,with the Central Bohai shoal as the warm center and surrounded by cold water(Bottom Cold Wa-ter Belt in Summer,BCWBS).The structure of"the asymmetric dual-center cold water"in the bottom layer of Bohai Sea in summer is reproduced.On this basis,the source of the BCWBS was analyzed by the conserved material tracing experiment and Lagrange particle tracking experiment,the formation mechanism of BCWBS is analyzed by topographic experiments,and the influence of the Central Bohai shoal on BCWBS is discussed.The results show that the low temperature water of BCWBS is mainly the residual cold water of the Bohai Sea in winter,the cold water intrusion from the North Yellow Sea also contributed to it.The shallow water depth of the Central Bohai shoal and the deeper topographic difference around the Central Bohai shoal are the main reasons for the formation of BCWBS.关键词
