摘　　要：根据2020年6月至2022年5月连续两年赛什腾山天文台和冷湖国家气象站气象观测数据,详细对比分析了降水量的精细化特征。结果表明:(1)赛什腾山天文台由于地形抬升使得水汽凝结,形成了较多的降水,年降水量为103.6 mm,降水日数达到50 d,远多于冷湖国家气象站,且昼间降水量大于夜间;(2)赛什腾山天文台各时次均有可能发生降水,但主要集中于6:00~18:00,较强的降水容易导致山体和地表冲刷,有造成地质灾害可能性;(3)赛什腾山天文台夏季以小到中雨量级降水为主,冬季则可发生大到暴雪过程,对天文观测的影响不大,但仍需注意大到暴雪的影响。Based on the meteorological observation data of Seshten Mountain Observatory and Cold Lake National Meteorological Station for two consecutive years from June 2020 to May 2022,the refined characteristics of precipitation are analyzed in detail.The results show that:(1)Due to the uplift of the terrain to make the water vapor condense,and the formation of more precipitation,the annual precipitation at Seshten Mountain Observatory is 103.6 mm,and the number of precipitation days reached 50 d,much more than the Cold Lake National Meteorological Station,and the daytime precipitation is greater than the night.(2)The precipitation at Seshten Mountain Observatory may occur at all times,but mainly concentrated in 6:00-18:00,and strong precipitation is easy to lead to mountain and surface erosion,which may cause geological disasters.(3)Seshten Mountain Observatory is dominated by small to moderate rainfall precipitation in summer,and large to heavy snowfall processes can occur in winter,which has little impact on astronomical observation,but it is still necessary to pay attention to the impact of large to heavy snow.
