WCR: Coupled Climatic-Hydrologic Change in the Terrestrial Water Cycle of North America in the 20th and 21st Centuries: Natural Variability and Anthropogenic Impacts

这个跨学科的项目组最近建立了一个新的模拟系统，用于探索气候-水文耦合过程，方法是将所有地表和地下陆地水库及其控制动态完全整合到一个最先进的区域气候模型--区域大气模拟系统(RAMS)中。利用这一工具，即RAMS水文学，项目组将产生区域气候变化对陆地水循环影响的缩小情景，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型，结合目前对过去几十年大规模气候变异性的理解，以及对未来潜在全球气候变化范围的估计，来研究20世纪和21世纪北美地区气候和水循环的耦合变化。首先，一名博士后助理研究员和一名研究生将参与研究。

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.
