Katabatic Winds in Eastern Antarctica

该奖项是与法国和澳大利亚科学家合作，对正在进行的东南极洲卡塔风研究的成果的更新。它依赖于两个自动气象站的地面气象数据；一个是从穹顶C到南极海岸，另一个是从英联邦湾到杜蒙德尔维尔海岸。将安装三个新的空间站，将该网络与澳大利亚南极计划维护的网络连接起来。这些新的观测站除了提供标准观测数据外，还将有能力提供热通量数据。扩大的覆盖范围将使人们能够检查天气系统对卡塔巴风的影响，并提供关于个别风速最大值的空间变异性的信息。此外，还将改进测量吹雪的仪器的校准，并将研究由赤道风造成的近海冰川的形成和热收支。

This award is an accomplishment-based renewal of an ongoing study of the katabatic winds in East Antarctica, in cooperation with French and Australian scientists. It depends on surface meteorological data derived from two lines of automatic weather stations; one from Dome C to the antarctic coast, the other along the coast from Commonwealth Bay to Dumont d'Urville. Three new stations will be installed, which will connect this network with that maintained by the Australian Antarctic program. These new stations will have the capability of providing heat flux data in addition to the standard observations. The expanded coverage will allow an examination of the influence of synoptic weather systems on the katabatic winds, as well provide information on the spatial variability of individual wind speed maxima. Additionally, improvements in the calibration of the instrument to measure blowing snow will be introduced, and the formation and heat budget of offshore polynyas resulting from katabatic winds will be studied.
