Continuation of a Study of the Windfield Near Terra Nova Bay

这笔赠款继续支持对Terra Nova Bay附近风场的研究，以及这些强风对罗斯海气旋生成的影响。这项工作是由怀俄明大学的T.Parish和俄亥俄州立大学的D.Bromwich合作完成的。冷空气沿着Terra Nova Bay附近形成海岸线的山脉中几个汇聚的缺口流下。由此产生的卡塔巴风是世界上最强、最持久的风之一。过去几年，提出者从各种来源收集了数据，包括仪表化的飞机测量、自动气象站、雪层的航空摄影和卫星图像。这项工作将继续分析现有数据，并继续从卫星和自动气象站收集更多数据。将开发模型来尝试解释观测到的风。一些自动气象站的数据是与位于Terra Nova Bay的意大利南极研究基地联合收集的。

This grant continues support for the study of the windfield near Terra Nova Bay and the effects of these strong winds on cyclogenesis in the Ross Sea. The work is performed by a collaboration of T. Parish at the University of Wyoming and D. Bromwich at Ohio State University. Cold air runs down the several converging gaps in the mountains that form the coastline near Terra Nova Bay. The resulting katabatic winds are among the strongest and most persistent winds in the world. The proposers have collected data for the past several years from a variety of sources, including instrumented aircraft measurements, automatic weather stations, airborne photography of snow formations and satellite imagery. This work will continue the analysis of existing data and the continued collection of additional data from satellites and the automatic weather stations. Models will be developed to attempt to account for the observed winds. Some of the automatic weather station data are collected in conjunction with the Italian Antarctic research base at Terra Nova Bay.
