| 摘 要： | 采用中山站和LGB69、EAGLE、DOME-A 3个南极内陆自动气象站的气象资料,分析了东南极中山站-DOME-A沿线风要素的分布特征。结果表明地处南极下降风下游的沿海陡坡区风力最强,越向内陆,风力越小;DOME-A地处内陆冰穹,没有下降风;而近沿海区由于受地形的影响,下降风十分明显,其风向以东北风为主,且大多发生在夏季夜间。

| Abstract: | Based on the data from Zhongshan Station and the three automatic weather stations at Antarctic ice sheet, LGB69, EAGLE and DOME-A, the characteristics of the surface wind along the track from Zhongshan Station to DOME-A are analyzed. It is found that wind speed over the deep coastal slope, which is the downstream area of the katabatic wind, is the greatest, and the further inland, the weaker the wind. Located at the highest point of Antarctic inland ice sheet, there is no katabatic wind at DOME-A. Influenced by the topography, the coastal area suffers obvious katabatic wind, with the main wind direction of NE, and most katabatic winds occurr at nights in summer. |
