摘要
根据 GAME- Tibet加强观测期间 ( 1 998年 5～ 9月 )所得到的位于青藏高原唐古拉山北坡的 D1 0 5站和南坡的 WADD站夏季风降水资料 ,对唐古拉山南北坡夏季风降水特征进行了初步的对比分析 .结果表明两地夏季风降水频率较高 .在 1 998年 6月 2 5日～ 9月 1 9日 ,WADD站的降水量比 D1 0 5站的降水量多 48.8% ,而发生的降水次数在 WADD站比 D1 0 5站多 1 0次 ,两者的累积降水次数基本上差不多 .同时 ,WADD站平均降水强度高于 D1 0 5站 .这两地的夏季风降水存在明显的活跃期和中断期 ,7月中旬夏季风降水都不活跃 .大多数情况下 ,这两地的日降水量的变化有较为一致的趋势 ,表明两地降水可能受同一降水过程的控制 .9月初以后 。
Based on the precipitation data of D105 station located in northern slope and WADD station located in southern slope of Tanggula Mountain over the Qinghai Xizang(Tibetan) Plateau obtained by GAME Tibet fieldwork group duing May-September, 1998, the features of summer monsoon precipitation are compared. The results show that the precipitation of each side occurs with high frequency. The precipitation at WADD is 48.8% more than that at D105. However, the accumulation frequency of precipitation at WADD is a little bit higher than that at D105. Meanwhile, the mean precipitation intensity at WADD is higher than that at D105. In most cases, the daily precipitation varies similarly on each side, it is shown that the precipitation processes on both sides could be similar.
