Hydrologic Response and Feedbacks to a Warmer Climate in Arctic Regions

研究人员将进行一个水文场和模拟计划，以更好地了解水文和植被在北极的相互作用。 气象和土壤活动层数据将收集在阿拉斯加西北部的苔原生态研究正在进行中的网站。 该协调项目正在研究气候变化对冻原生态的作用，这可能是对全球变暖的反应。 将收集雷达图像和实地数据，并用于水文和气候模型，用于预测阿拉斯加北坡在温暖气候条件下的未来环境条件。 这项水文研究对于了解降水，径流和土壤水分对整个北极苔原地区可持续性的作用至关重要，全球气候模型预测全球变暖的影响最大。

Meteorological and soil active layer data will be collected at sites in northwestern Alaska where tundra ecological studies are underway. The coordinated project is examining the role of climate change on tundra ecology that could occur in response to global warming. Radar imagery and field data will be collected and used in hydrologic and climate models that are used to project future environmental conditions on the Alaska North Slope under warmer climate conditions. This hydrological study is critical to understanding the role of precipitation, run-off, and soil moisture on the sustainability of tundra regions throughout the Arctic where global climate models predict the greatest effects from global warming.
