This interdisciplinary project team has recently built a new modeling system for exploring coupled climatic-hydrologic processes by fully integrating all surface and subsurface terrestrial reservoirs, and their governing dynamics, into a state-of-the-art regional climate model, the Regional Atmospheric Modeling System (RAMS). With this tool, i.e., RAMS-Hydrology, the project team will produce downscaled scenarios of regional climate change impacts on the terrestrial water cycle and investigate the two-way interactions between the atmospheric, surface, and subsurface reservoirs that modulate these impacts. The study will employ the model, along with current understanding of large-scale climate variability over the past decades and estimates of the range of potential global climate changes in the future, to examine coupled climate and water cycle change over North America in the 20th and 21st centuries. First a post-doctoral research associate and subsequently a graduate student will be involved in the research.

这个跨学科的项目团队最近建立了一个新的建模系统，通过将所有地表和地下陆地水库及其管理动态完全集成到最先进的区域气候模型中，探索耦合的气候水文过程，即区域大气建模系统（RAMS）。使用此工具，即，RAMS水文，项目团队将产生区域气候变化对陆地水循环影响的缩小比例的情景，并调查调节这些影响的大气，地表和地下水库之间的双向相互作用。这项研究将利用该模式，沿着目前对过去几十年大规模气候变化的了解和对未来潜在全球气候变化范围的估计，审查20世纪和21世纪北美气候和水循环的耦合变化。首先是博士后研究助理，然后是研究生将参与研究。
