摘　　要：利用冷湖赛什腾山山顶天文台址区域自动气象站、冷湖国家基准气候站2021年12月至2023年12月气象观测资料,应用数理统计方法对比分析冷湖赛什腾山天文台址气温变化特征及对天文观测选址和观测活动的影响。分析结果表明,赛什腾山山上年平均气温-2.5℃,较冷湖镇偏低7.2℃,气温年较差和日较差较冷湖镇小;秋冬季节温度低,空气干燥,天气条件对天文观测较有利;对天文观测设备机械结构运行稳定性以及望远镜指向精度准确性评估有一定的参考价值,为天文台址建设和天文观测活动、设备维护等提供科学依据。Using the meteorological observation data from the regional automatic weather station and the national reference climate station at Lenghu Saishiteng Mountain observatory site from December 2021 to December 2023,and by applying mathematical and statistical methods for comparative analysis,the characteristics of temperature variation at Lenghu Saishiteng Mountain observatory site and their impact on the selection of astronomical observation sites and observation activities are examined in this paper.The analysis results showed that the annual average temperature of Saishiteng Mountain is-2.5℃,which is 7.2℃lower than that of Lenghu Town,and the annual and daily temperature ranges are smaller than that of Lenghu Town.In autumn and winter,the temperature is low,the air is dry,and the weather conditions are favorable for astronomical observation.The findings also have certain reference value for assessing the stability of the mechanical structure of astronomical observation equipment and the accuracy of telescope pointing,providing a scientific basis for the construction of astronomical observatory sites,astronomical observation activities,and equipment maintenance.
