摘要
针对现有的模型不能满足新疆地区加权平均温度的高精度应用问题,该文讨论了几种常用计算方法的优缺点,然后利用新疆地区8个探空站2004—2014年的数据,采用多元线性回归分析的方法建立了新疆地区的加权平均温度区域模型。经过与其他已研究模型进行统计分析,同时利用中尺度数值天气预报(WRF)模式拟合气象元素值对各模型进行了检验,结果表明该文所建立的对流层加权平均温度模型更适应于新疆地区。
Aiming at the problem that the existing model has a larger error in Xinjiang region,this paper analyzed the advantages and disadvantages of several methods for calculating weighted mean tropospheric temperature.Then a weighted mean tropospheric temperature model suitable for the Xinjiang region by multiple linear regression analysis was established through using the radiosonde data of 8 stations from 2004 to 2014 at Xinjiang.At the same time,according to other researcher’s research,a variety of models were created by the same data.After statistical analyzing with the models,and calibrating by weather research and forecasting model(WRF)value,the results showed that the weighted mean tropospheric model established in this paper was more adapted to Xinjiang region.
