9320938 Curry This project is an integrated experimental and modeling effort to understand and interpret the evolution of sea ice characteristics, cloud properties, and radiation fluxes during the autumnal freezing of the coastal waters of the Beaufort Sea. It will carried out in the scientific context of the Beaufort and Arctic Seas Experiment (BASE), a Canadian program whose objective is an improved understanding of weather systems in the Canadian Arctic, and whose focus is the hydrologic balance of the Mackenzie River. This project will make use of the NCAR C-130 aircraft, and BASE will provide substantial synergistic observational facilities. The direct aircraft observations will be supplemented by satellite data to extend the time and space scales of the analyses, and will be used to interpret and validate satellite retrieval algorithms. A three-dimensional mesoscale model of the atmosphere will be used to interpret the temporal and spatial evolution of the sea ice cover and the atmospheric boundary layer characteristics. A coupled sea ice model will be used to interpret the physical processes of the sea ice that respond to atmospheric forcing. The result of the research will be an improved understanding of the atmospheric modulation of the surface radiation balance and the effect of the radiation balance on the freezing of coastal waters. ***

9320938咖喱这个项目是一项集成的实验和建模工作，旨在理解和解释Beaufort Sea沿海水域秋天的秋季冻结期间海冰特征，云特性和辐射通量的演变。 它将在Beaufort和Arctic Sean实验的科学背景下进行，这是一个加拿大计划，其目标是对加拿大北极的天气系统的了解，其重点是Mackenzie河的水文平衡。 该项目将利用NCAR C-130飞机，基地将提供实质性的协同观察设施。 直接的飞机观察结果将通过卫星数据补充，以扩大分析的时间和空间尺度，并将用于解释和验证卫星检索算法。 大气的三维中尺度模型将用于解释海冰覆盖的时间和空间演化以及大气边界层特征。 耦合的海冰模型将用于解释对大气强迫反应的海冰的物理过程。 研究的结果将是对表面辐射平衡的大气调节的了解以及辐射平衡对沿海水域冻结的影响。 ***
