Collaborative Research: Land-Atmosphere Interactions in Beringia Over the Last 21,000 Years: An Investigation of Climate Feedback Using the Arctic Regional Climate System Model

该奖项授予科罗拉多大学、俄勒冈大学、华盛顿大学和阿拉斯加大学的一项合作研究，旨在提高对过去21,000年来与贝林吉亚植被、海平面和地表水变化相关的特征、机制和反馈过程的理解，并利用这种理解来帮助开发对未来泛北极气候变化的预测工具。具体的研究目标和任务是在完善模拟区域古气候变化和诊断气候系统不同组成部分之间相互作用的模拟战略的基础上，利用全球和区域气候模型和平衡植被模拟模型。模拟将在关键时间进行，与观测数据进行比较，并进行诊断以了解潜在的反馈。

The award is for a collaborative study involving the Universities of Colorado, Oregon, Washington, and Alaska, aimed at improving the understanding of the characteristics, mechanisms, and feedback processes associated with changes in vegetation, sea level, and standing surface water in Beringia during the last 21,000 years, and to use this understanding to aid in the development of predictive tools for future pan-Arctic climate change. The specific research objectives and tasks are based on refining a modeling strategy for simulating regional paleoclimatic variations and for diagnosing the interactions between different components of the climate system, utilizing global and regional climate models and an equilibrium vegetation simulation model. Simulations will be performed at key times, compared to observational data, and diagnosed to understand potential feedbacks.
