Collaborative Research: pre-RIME Studies of Transport Processes in the Ross Sea Sector

该合同将提供资金，在南极洲罗斯岛以东和以南地区部署七个自动气象站(AWS)，以确定罗斯冰架主要气流走廊周围的地表环境。这些气流被确认为南极洲和亚极纬度之间质量、热量和动量传输的主要走廊。了解这些气流的基本物理特征以及罗斯海北部频繁的气旋活动对它们的调制，对于提高我们预报罗斯岛和麦克默多地区天气的能力是必要的。以前的工作已经确定，罗斯海地区在南极过程与地球其他地区在各种时间尺度上的联系中至关重要。这项为期两年的研究将包括自动气象站的部署、现有数据集的分析和模型模拟的启动，并将成为计划中的罗斯岛气象实验的基础之一。

This award will provide funds to deploy an array of seven automatic weather stations (AWS) in the region to the east and south of Ross Island, Antarctica, in order to characterize the surface environment surrounding the major air flow corridors on the Ross Ice Shelf. These air streams have been identified as the primary corridor for the transport of mass, heat, and momentum between Antarctica and subpolar latitudes. An understanding of the basic physical characteristics of these air streams and their modulation by the frequent cyclonic activity in the Ross Sea to the north is necessary to advance our capabilities in forecasting weather in the Ross Island and McMurdo area. Previous work has established the Ross Sea region as critically important in the connection of Antarctic processes to the rest of the globe on a variety of time scales. This two-year study will include AWS deployment, analysis of existing data sets and the initiation of model simulations, and will form one of the bases of a planned Ross Island Meteorological Experiment.
