摘要
通过采用一种较好地考虑了海气通量交换对下垫面特征非线性依赖的通量计算方案,利用较成熟的逐日通量距平耦合方案实现了次网格尺度海冰非均匀条件下一个全球大气环流模式和一个全球海洋环流模式在高纬地区的耦合,并完成了一个50年的长期积分。模拟结果表明,通量计算方案中水道的作用是合理的,耦合模式能较好地模拟出北半球高纬海冰的主要地理分布特征,但夏季北冰洋内部靠近欧亚大陆部分边缘海区海冰密集度偏大。
A sea ice effect representation scheme which consider the nonlinear dependence of sea-air flux exchange on underlying surface characteristics better is used here to deal with the sub-grid scale sea ice inhomogenities in a coupled model. The coupled model has been integrated for 50 years and the simulated results of sea ice in high northern latitudes have been analyzed and validated. The results show that the sea ice effect representation scheme is rational and that the coupled model can reproduce the main geographical distribution features of sea ice in high northern latitudes well.
