| 摘 要： | 利用t检验法对青海省海西所属7个站气温、气压、相对湿度、平均风速、0~320cm地温年平均值序列进行显著性检验;在人工与自动观测资料对比差值分析的基础上,建立人工与自动观测要素间的回归方程,对年序列差异显著的要素进行回归订正和效果对比分析。结果表明,自动替换人工观测对海西7个站各气象要素年平均值序列均一性产生了不同程度的影响,多个站多个要素不连续;统计人工与自动观测要素资料月平均对比差值,用一元线性回归法进行订正,订正后的序列基本消除了自动观测替换人工观测的差异,实现了观测资料的均一性和延续性。

| Abstract: | Using t test to seven haixi prefecture, qinghai province belong to stand the temperature, pressure, average wind speed, relative humidity, 0-320 cm geothermal years average significance test sequence; Difference in manual and automatic observation data contrast analysis, on the basis of establishing regression equation between the manual and automatic observation elements, elements of significant difference in sequence regression correction and effect analysis.Resultsshow that the automatic replacement of artificial observation of hercynian 7 stand various meteorological elements annual average series uniformity had different degrees of influence, discontinuous multiple station elements; Statistical manual and automatic observation data elements month average contrast difference value, correction using monadic linear regression method, after reduction of the sequence of basic eliminates automatically replace artificial observations, and the difference of observation data uniformity and continuity is realized. |
