Investigations of Katabatic Wind and its Interaction with Sea Ice

9413879温德勒这个项目是一项国际合作(美国-法国-澳大利亚)关于南极东部海岸卡塔巴风的研究，基于两条自动气象站，一条从法国内陆到圆顶C，另一条沿着海岸。海岸阵列包括丹尼森角和马丁港的气象站，这两个站记录了全球最高的平均地表风速。这些风将海冰推向近海，并导致从海洋到大气的极高热通量。卫星主动微波成像(合成孔径雷达)将与观测的气象数据相结合，以分析近海冰川的形成、持久性和大小随风速的变化。沿海气象站阵列将增加三台仪器，阿拉斯加大学合成孔径雷达数据接收站将用于下载南极洲东部的图像。这些图像将补充来自霍巴特的澳大利亚接收站的图像，以及当其投入使用时，来自麦克默多的Radarsat接收站的图像。***

9413879 Wendler This project is an internationally collaborative (U.S.-French- Australian) study of katabatic winds along the coast of East Antarctica, based on two lines of automatic weather stations, one from the French station inland to Dome C, the other along the coast. The coastal array includes stations at Cape Denison and Port Martin, which have recorded the highest average surface wind speeds on the globe. These winds drive the sea ice offshore, and are responsible for extremely high heat fluxes from the ocean to the atmosphere. Satellite-based active microwave imagery (Synthetic Aperture Radar) will be combined with the observed meteorological data to analyze the formation persistence and size of offshore polynyas as a function of wind speed. The coastal array of weather stations will be augmented by three additional instruments, and the University of Alaska receiving station for Synthetic Aperture Radar data will be utilized to downlink images of East Antarctica. These images will be supplemented with images from the Australian receiving station in Hobart, and, when it becomes operational, from the Radarsat receiving station at McMurdo. ***
