Abstract

Abstract:

Based on hourly temperature elements from the new and old meteorological stations in Kangle of Gansu Province in 2012，the
temperatures of the new station were compared to the old station with corresponding period． The results showed that the temperature be-
tween the new and old stations had significant difference． The monthly mean，maximum and minimum temperatures of the old site were
higher than those of the old site，and the difference of the minimum temperature at two sites was biggest． This indicated that urban heat
island effect of the old site was obvious． The duration of daily temperature difference in summer was longest，following spring and win-
ter． In additional，temperature of the new and old stations had a significant positive correlation，and the correlation coefficients were a-
bove 0． 99． Thus，the linear regression equation of temperature was built between the new and old sites． The temperature of the old
sites revised by equation appeared to overlay basically with the new site．

Key words: moving station, temperature, comparative analysis, Kangle

摘要：

利用 2012 年气温要素逐日资料，对甘肃省康乐县气象观测站新旧站址同期气温观测资料进行对比分析。发现 2 站之间气温存在明显负温差，旧测站各月平均气温、最高气温、最低气温均高于新测站，且最低气温相差最大，说明旧测站城市热岛效应明显，城市热岛效应以提升最低气温减小气温日较差方式来提高旧测站的气温;新旧测站气温之间存在极显著的线性正相关关系，可建立新旧测站之间气温线性回归订正方程，订正后的新旧测站气温要素基本重合。
