This project will attempt to quantify the effects of variations in the major ice-atmosphere energy budget terms on the arctic sea ice concentration and distribution. Observational studies have shown the existence of a variety of interrelationships between the atmosphere and the sea ice, but modeling studies are required to identify and quantify forcing mechanisms, directions of operation, and the sensitivity of the interactions to changes in the state of the ocean and the atmosphere. Specifically, this project will make use of a ten-year data set to construct forcing functions for a coupled sea ice-radiative transfer model. Sensitivity studies will be conducted to identify specific climatically interesting regions, to determine if intense short- term events affect the long-term sea ice state, and to define the overall limits of the arctic climate system.

这个项目将试图量化变化的影响 在北冰洋主要的冰-大气能量收支条件下， 冰的浓度和分布。 观察性研究 显示了各种相互关系的存在， 大气和海冰，但需要进行建模研究 确定和量化强迫机制， 操作，以及相互作用对 海洋和大气的状况。 具体来说， 该项目将利用十年的数据集来构建强迫 海冰-辐射传输耦合模型的函数。 将进行敏感性研究以确定特定的 气候有趣的地区，以确定是否激烈的短- 长期事件影响长期海冰状态，并定义 北极气候系统的整体极限。
