安定国家气象观测站新站与旧站气象观测资料对比分析

Comparative Analysis of Meteorological Observation Data Between New Station and Old Station of Anding National Meteorological Observatory

利用2018年1月1日至12月31日安定国家气象观测站新站、旧站常规气象观测资料,采用双样本t检验方法进行检验,对新旧站主要气象要素进行对比分析。结果表明,安定新站与旧站气象基本观测资料具有较好的一致性,新站气温低于旧站,年降水量、年平均相对湿度、年平均风速大于旧站,风向相符率低。

Based on the conventional meteorological observation data of new station and old station of Anding National Meteorological Observatory from January 1 to December 31,2018,the double sample t-test method was used to test and analyze the main meteorological elements of the new and old stations.The results showed that the basic meteorological observation data of Anding new station and old station had the high consistency;the temperature of the new station was lower than that of the old station,but the annual precipitation,the annual average relative humidity and the annual average wind speed of the new station were higher than those of the old station;the coincidence rate of wind direction between the two stations was low.
