The proposed research addresses the question "How will the coupled arctic climate system respond to changes in riverine discharge of freshwater, and how to the temporal and spatial variability of freshwater discharge and changes therein interact with the dynamics of high latitude climate?". The project proposes to perform a series of numerical simulations using existing models that incorporate sea ice, atmosphere and ocean processes. Science questions will be posed through model runs in which sea ice, ocean, and land surface models are run off-line, and aspects of the off-line climatologies will be prescribed in partially coupled runs of the fully coupled system. The results of the partially coupled runs will be compared with results of fully coupled, ensemble climate simulations in order to isolate the effects of interactions among the land, sea ice, ocean and atmosphere.

拟议的研究解决了一个问题：“耦合的北极气候系统将如何应对淡水河流排放的变化，以及如何与淡水排放的时间和空间变异性以及其中的变化与高纬度气候的动态相互作用？”。 该项目建议使用现有模型进行海冰，大气和海洋过程进行一系列数值模拟。 科学问题将通过模型运行提出，在该模型中，海冰，海洋和陆地表面模型是离线运行的，离线气候的各个方面将以完全耦合系统的部分耦合运行中的部分规定。 部分耦合跑步的结果将与完全耦合的集合气候模拟的结果进行比较，以隔离土地，海冰，海洋和大气之间的相互作用。
