甘肃崆峒站新旧址对比观测资料分析

为了解甘肃崆峒国家基本气象站新旧址气象要素对比观测数据差异,选用2016年1～12月新站和旧站气温、气压、相对湿度、风向风速、降水量等要素资料进行对比分析,重点利用均值差异、相关与回归、显著性检验等统计方法分析了新旧测站气温差异及产生原因,结果表明：新址气温、气压均低于旧址,风速高于旧址,降水量、相对湿度差异大,变化无规律,其产生的主要原因是地理位置、海拔高度及观测场周边环境的不同造成；新址与旧址气温存在高度正相关,两站气温差异不显著,可以合并计算,研究结果可为资料使用者提供订正的依据。

Contrast analysis on discrepant observation data in kongtong basic meteorological station of gansu province

According to the comparative observation data in the new and the old kongtong national basic weather station of Gansu province ,this paper ananlysed meteorological factors of temperature, air pressure, relative humidity, quantity of precipitation, wind direction and speed during the months from Jan.2016 to Dec.2016. The difference of temperature between the new and old site observations and its causes were analyzed by using statistical methods including mean differences, correlation and regression and significant test, etc. It found that the average daily temperature and air pressure of the old station were higher than the new one. The average wind speed of the old station was smaller than the new one.The change of relative humidity and precipitation were irregular. Meanwhile, it also analyzed the main reason that caused the differences of the meteorological factors by site geography ,building block and ultitude in the surrounding environment. Statistical results show that there was significant positive correlation between the new and old site observations, the difference of temperature was not significant, so temperature can be incorporate.
