摘要
1991年中山站越冬海洋气象考察,主要是对南极中山站气温、气压、云量、风向风速,大气湿度和日照时间,进行日常地面气象观测,取得每日四次现场观测资料,对各种气象要素进行分析统计,并与前二年气象资料进行了对比,得出了1991年中山站地区,风暴多,风速大,气温比前年高的气象特点。在越冬期间还对中山站海冰、湖冰厚度进行测量,掌握沿岸海冰各月分布变化情况。1991年中山站最大风速达46.2m/s,这是中山站建站以来所观测到的最大风速。冬季最低气温为-28.6℃也是建站以来最高一年。
The main activities of marine meteorological group wintering in Zhongshan station in 1991 included observation of air temperature, Pressure cloudiness, wind speed, wind direction, air humidity and solar radiartion. In this paper, these data were analysed and compared with those observed in the previous two years.It is obtained that the-rewere ore storms, stronger wind and higher air temperature in 1991 than in previous years.In the winter time we measured the thickness of sea and lake ice, around zhongshan station and observed the sea ice distribution near shore. The greatest wind speed and the lowest air temperature in 1991 are 46.2m/s and -28.6℃respectively, which are historically the extreme values in zhongshan station.
