Analysis of Temperature Variation Characteristics at Lenghu Saishiteng Mountain Observatory Site
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.
