Hydrologic Linkages with Arctic Freshwater and Terrestrial Systems

OPP-9318535凯恩气候模型的发展强烈强调了这样一个事实，即几乎所有控制气候的重要过程都是相互作用的，理解这些过程之间的联系至关重要；例如，水文系统在连接大气和陆地过程中的作用是什么。作为ARCS LAII通量研究的一个组成部分，该项目的目标是增进对大气、陆地和水生系统之间联系的了解；具体地说，这意味着对水文状况的能量和质量转移过程有一个定量的了解。这项研究的一个主要组成部分是一个现场测量计划，以量化物理上截然不同的流域(例如，与沿海平原相比，山麓的流域)的水量平衡，以及从北冰洋到布鲁克斯山脉整个地区的能量平衡。一个目标是开发一种基于物理的、空间分布的水文模型，当与LAII研究人员合作的结果结合在一起时，该模型可以与流域的生物地球化学过程相结合。其他目标是了解影响雪分布的机制，以及整个库帕鲁克流域水和能量横向和垂直通量的工作模式。***

OPP-9318535 Kane Development of climatic models has intensely highlighted the fact that almost all of the important processes controlling climate are interactive and that it is vital to understand the linkages between these processes; for example, what is the role of the hydrologic system in connecting atmospheric and terrestrial processes. As a component of the ARCSS LAII Flux study, the objective of this project is to improve the understanding of the linkages between atmospheric, terrestrial, and aquatic systems; specifically, this means developing a quantitative understanding of the energy and mass transfer processes of the hydrologic regime. A primary component of this study is a field measurement program to quantify the water balance of watersheds that are physically quite different (for example, watersheds in the Foothills compared to those on the Coastal Plain) and an energy balance of the entire region from the Arctic Ocean to the Brooks Range. One goal is to develop a physically based, spatially distributed hydrologic model that, when combined with the results of cooperating LAII researchers, can be coupled with the biogeochemical processes of a watershed. Other goals are to develop an understanding of the mechanisms which impact snow distribution and a working model of lateral and vertical fluxes of water and energy in the entire Kuparuk watershed. ***
