| 摘 要： | In this paper,based on the observational data of 1995in the Chinese Antarctic Great Wall Station the snowstorm is studied synoptically.It is found that there are two kinds of snowstorms with different physical characteristics and that the happening of snowstorm is always accompanied by a near-ground level inversion laycr.The function of the inversion layer is analyzed,too,It is indicated that thestrong ESE-wind type snowstorm is mainly caused by katbatic wind and gradient wind together.This idea is new and different from the general concept that there is no katabatic wind in the westerm Antarctic area.

| Abstract: | In this paper, based on the observational data of 1995 in the Chinese Antarctic Great Wall Station the snowstorm is studied synoptically. It is found that there are two kinds of snowstorms with different physical characteristics and that the happening of snowstorm is always accompanied by a near-ground level inversion layer. The function of the inversion layer is analyzed, too. It is indicated that the strong ESE-wind type snowstorm is mainly caused by katabatic wind and gradient wind together. This idea is new and different from the general concept that there is no katabatic wind in the western Antarctic area. |
