基于贵阳、威宁两个无线电探空站2014~2016年的气象数据，采用一元线性回归方法构建贵州整体、局地及季节大气加权平均温度Tm模型，并分析模型的精度。结果表明，贵州整体Tm模型精度高于Bevis模型、全国模型和亚热带季风气候模型；建立贵州局地、季节模型有助于进一步改善Tm的精度；相较于Bevis模型，局地Tm模型反演的PWV精度更高，与实际降水吻合更好。"/>
Model Establishment and Accuracy Analysis of Atmospheric Weighted Mean Temperature in Guizhou Region" />
Based on the meteorological data of the two radiosonde stations in Guiyang and Weining from 2014 to 2016, the overall, local and seasonal atmospheric weighted mean temperature models of Guizhou are constructed by the one-dimensional linear regression method. Model accuracy is analyzed. The results show that the accuracy of Guizhou model is higher than that of the Bevis, national, and subtropical monsoon climate models.Meanwhile, the establishment of Guizhou local and seasonal models contribute to further improve accuracy. Compared with the Bevis model, the local model inversion has higher PWV accuracy and is in better agreement with actual precipitation."/>
