蓟州国家气象观测站迁站数据对比分析及评估

Comparative Analysis and Evaluation of Relocation Data of Jizhou National Meteorological Observation Station

本文采用对比观测资料差值、差值标准差、降水量累计相对差值、风向相符率及显著性检验等资料评估技术方法,对蓟州国家气象观测站2015年1—12月迁站前后新、旧站观测资料进行综合分析。结果表明:新址各对比观测要素数据与旧址同期观测的数据差异不大,一致性较高;新、旧址个别月份相对湿度、风速等要素离散性较大,主要原因为周边探测环境的改变。新址观测资料具有可用性。

In this paper,the observation data of Jizhou National Meteorological Observation Station before and after relocation from January to December in 2015 were comprehensively analyzed by means of data evaluation techniques such as comparison observation data difference,standard deviation difference,accumulated relative difference of precipitation,wind direction coincidence rate and significance test.The results showed that there was little difference of observation data between the new site and the old site at the same period,and the consistency was high.The relative humidity,wind speed and other factors of the new site and the old site had a great dispersion in individual months,which was mainly due to the change of surrounding detection environment.The observation data of the new site was available.
