【摘要】利用中国南极科学考察队 1 998年 1 2月至 1 999年 1月在东南极格罗夫山地区地质考察期间所获得的天气资料 ,对该地区的温度、雪面温度、风速、风向等天气要素进行了分析。结果表明 :夏季格罗夫地区温度日变化和盛行风向与中山站相类似 ,但温度日较差和强风频率比中山站大。当受来自北方暖湿气流影响时 ,常出现降雪天气 ;在东风气流控制下 ,天气以晴为主

【Abstract】WT5BZ]The summer weather characteristics of Grove Mountain are presented based on the data obtained by Chinese National Antarctic Research Expedition (CHINARE) in Jan. 1999. The result shows that the pattern of diurnal variation of temperature and the prevailing wind direction in Grove is similar with that in Zhongshan Station. However, the daily range of temperature and strong wind frequency are much higher than that of Zhongshan Station. The change of wind direction correlates with weather system that impacted Grove area. The warm and wet air from northern parts often causes the precipitation. The clear weather appears controlled by eastern winds in January. [WT5HZ]
