摘要:

利用 1 994年 1 2月~ 1 995年 1 1月在南极长城站考察期间的观测资料和所收取的气象传真图对长城站的晴好天气作了天气学研究 ,主要从气压场、温湿场和高空层结等方面进行了天气学分析 ,找出了高温、高湿和低温、低湿两类物理性质不同的晴好天气过程 ,并用实例对比分析说明了他们的形成是副热带高压南伸与极地高压北扩控制该区的结果 ,为预报晴好天气提供了天气学依据

Abstract:

Based on the observational data and the facsimile charts from Dec.1994 to Nov.1995 of Chinese Antarctic Great Wall Station, fine weather there was studied. The pressure field, temperature relative humidity field and aerological stratification were analyzed synoptically. Two kinds of fine weather with different physical characteristics were found and analyzed. The results provide a basis for local weather forecast.
