Collaborative Research: Modeling Hydrologic Processes in the Arctic: A Watershed Approach for Regional and Global Climate Models

该项目将修改现有的基于集水区的陆地表面模型，以包括雪和冻融动态对北极冻土带水文的影响。该模型的发展将填补目前可用模型的空白，这些模型没有考虑到冰雪物理、永久冻土动力学和地形对冻土带水文的综合影响。目前的缺乏严重限制了旨在了解和预测气候变化对北极生态系统影响的努力。通过解决这个问题，这个项目将对我们了解北极对气候变化的反应能力产生重大影响。

The project will modify an existing catchment-based Land Surface Model to include the effects of snow and freeze-thaw dynamics on Arctic tundra hydrology. The development of this model will fill a gap in currently available models that do not incorporate the combined effects of snow physics, permafrost dynamics and topography on tundra hydrology. The current deficiency has severely limited efforts aimed at understanding and predicting the effects of climate change on arctic ecosystems. By addressing this problem this project will have a major impact on our understanding of the responsiveness of the Arctic to climate change.
