站址迁移对高要站气候资料序列的影响和分析

对广东省高要市气象站迁站前20a和迁站后5a的气象资料统计分析,找出迁站前后观测资料序列差异较大的气象要素,分析其引起差异的原因。经对本站及邻站四会、德庆站同期相关资料序列进行了"t检验分析",高要站资料序列差异性显著,而四会、德庆站的资料序列的差异性不显著,说明高要站迁移前与迁移后的资料序列的差异并非由气候变化引起,而新旧站的地理环境差异才是造成资料序列差异的主要原因。

Effect of Gaoyao Station Migration on Climatic Data

With an analysis on the statistics of meteorological data,the elements with great difference before and after Gaoyao station migration are selected and the causes give rise to the difference is analyzed.The t test is utilized on Gaoyao station,Sihui station and Deqing station to examine the confidence levels of their differences between the new and the old address.Results show that the general mean climate fields are not obviously different on Sihui and Deqing stations while Gaoyao is remarkable,which indicates that the main reason for the differences of climatic data before and after Gaoyao station migration is not caused by climatic variances but the change of the geographic environment.
