Coupling a Thickness-Distribution Model of Sea Ice with Vertical Temperature Resolution to the NCAR Climate System Model

提出的探索性研究将尝试将具有垂直温度分辨率的海冰厚度分布模型与NCAR CSM相结合。冰厚分布模型可在亚网格尺度上解析多个厚度类别，并允许对冰变形进行明确的处理。冰的厚度分布模式和垂直温度分辨率影响冰的生长和衰变以及大气和海洋之间的热量和水分交换。这些过程影响高纬度气候的平均状态和敏感性。厚度分布模型在严格节约能量的同时，独特地解决了海冰的垂直温度分布，与传统方法相比，可以集成更少的类别。这项工作很重要，因为它将改进CSM中的海冰模型，使其使用更现实的热力学。

The proposed exploratory research will attempt to couple a thickness-distribution model of sea ice with vertical temperature resolution to the NCAR CSM. An ice thickness distribution model resolves multiple thickness categories on the sub-grid scale and allows an explicit treatment of ice deformation. Inclusion of an ice thickness-distribution model and vertical temperature resolution in the ice affects ice growth and decay as well as the exchange of heat and moisture between atmosphere and ocean. These processes influence the mean state and sensitivity of high latitude climate. The thickness distribution model uniquely resolves a vertical temperature profile in the sea ice while strictly conserving energy and can be integrated with fewer categories than traditional methods. The work is important because it will result in an improved sea ice model in the CSM, one that uses more realistic thermodynamics.
