Hydrologic Response and Feedbacks to a Warmer Climate in Arctic Regions

研究人员将进行一个水文场和建模程序，以更好地了解北极的水文学和植被是如何相互作用的。气象和土壤活动层数据将在阿拉斯加西北部正在进行苔原生态研究的地点收集。这个协调项目正在研究气候变化对冻土带生态的影响，这可能是为了应对全球变暖而发生的。雷达图像和实地数据将被收集并用于水文和气候模型，这些模型用于预测气候变暖条件下阿拉斯加北坡未来的环境条件。这项水文学研究对于理解降水、径流和土壤湿度对整个北极冻土带地区可持续性的作用至关重要，在这些地区，全球气候模型预测了全球变暖的最大影响。

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.
