AbstractATM-9908657Entekhabi, DaraMassachusetts Institute of TechnologyTitle: The Impact of Snow Anomalies on Interannual Northern Hemisphere Climate VariabilityThe proposed work aims at establishing the snow cover and land surface forcing link to seasonal-interannual climate variability in the Northern Hemisphere. A conceptual model will be developed based on land-atmosphere interactions that will explain a significant portion of the climate variability associated with such modes of the atmosphere as the North Atlantic Oscillation. The ways in which the conceptual model could serve as the basis for a seasonal to an interannual forecast system will be investigated. The work is important because it will yield improved understanding of the role of snow in climate.

摘要ATM-9908657 Entekkorne，达拉麻省理工学院题目：积雪异常对北方半球气候年际变率的影响这项工作的目的是建立积雪和陆地表面强迫与北方半球季节-年际气候变率的联系。将根据陆地-大气相互作用建立一个概念模型，解释与北大西洋涛动等大气模式有关的气候变异的很大一部分。将研究概念模式如何作为季节性到年际预报系统的基础。这项工作很重要，因为它将提高对雪在气候中作用的理解。
