| 摘 要： | 本文根据1983和1984年横断山脉中段云岭白茫雪山东坡三个不同拔海高度(4292m、3760m和2025m)上测量的太阳直接辐射资料,计算并分析了云岭白茫雪山林克大气混浊因子T_P。T_P随拔海高度的升高而减小,不同拔海高度上T_p的年变化趋势基本一致,最大值出现在7、8月份,最小值在11月份。若将T_P分成气溶胶混浊因子T_R和水汽混浊因子T_W(T_P=1+T_R+T_W),水汽混浊因子T_W的年变化趋势与降水分布相吻合,气溶胶混浊因子T_R呈相反的变化趋势。地处干热河谷的奔子拦,由于局地气候的影响,其混浊度较大,接近海拔50m的北京,年平均值为3.09。

The atmosphere turbidity Coefficient of Yunling Baimang Snow Mountain in the central part of the Hengduan Mountain Range |

| Abstract: | According to the data of solar direct radiation observation at the Yunling Bai-mang Snow Mountain in the cenTRal part of the Hengduan Mountain Range in 1983 and 1984,the Linke atmosphere turbidity coefficient TP was calculated and analysed. It's found that TP decreases with the increase of altitude. The annual variations of TP show similar TRend at different altitude.TP is maximum in July and August, and TP is Minimum in November. TP may he divided into the aerosol turbidity coefficient TR and the vapour turbidity coefficient TW, The annual variation of TW is in accordance with the annual disTRibution of the precipitation, and TR shows the opposite variation tendency. |
