摘要

摘要: 以渤海1998~1999和2000~2001年度冬季的海冰发展过程为例,采用实时气象数值预报场作为大气强迫,利用渤海冰海洋耦合模式模拟渤海整个冬季的海冰生消和演变以及渤海冰季冰气、冰水和气水界面的热收支.模拟结果显示大气和海洋的热力效应对渤海的海冰发展非常重要,特别在海冰的冻结和融化阶段,海洋热通量在热力耦合中起着重要作用.模拟还显示了冰覆盖内部区域和冰外缘线附近不同的热力特征,分析讨论了冰区内和冰边缘两个特征点冰厚分布、界面热量收支和海表水温等.

Abstract: The coupled ice-ocean model for the Bohai Sea is used for the simulating the freezing,melting, and variation of ice cover and the heat balance at the sea-ice,air-ice,and air-sea interfaces of the Bohai Sea during the entire winter in 1998~1999 and 2000~2001.The coupled model is forced by real time numerical weather prediction fields.The results show that the thermdynamic effects of atmosphere and ocean are very important for the evolvement of ice in the Bohai Sea,especially in the period of ice freezing and melting.Ocean heat flux plays key role in the thermo dynamic coupling.The simulation also presents the different thermodynamic features in the ice covered region and the marginal ice zone.Ice thickness,heat budget at the interface,and surface sea temperature,etc.between the two representative points are discussed.
