| 摘 要： | 利用中国区域内93个无线电探空站2005-2010年的探空数据,分析加权平均温度的特征,并分析Bevis公式在中国的适用性。同时利用北京站2005-2010年的无线电探空数据进行北京地区加权平均温度模型的本地化研究,并利用模型进行北京地区2011年加权平均温度的计算,其结果与实际加权平均温度的差值平均值为2.16K,均方根误差为4.78,同时将利用模型生成的可降水汽量与利用探空数据获得的可降水汽量进行对比,差值平均值为-1.42K,均方根误差为2.87。实验证实北京地区本地化模型的精度较高,实用性较强。

| Abstract: | Based on the data of 2005- 2010 of 93 radiosonde stations in China, the characteristics of weighted mean temperature（Tm） are analyzed, and the applicability of the Bevis formula in China is also reasearched. Data of 2005-2010 of Beijing radiosonde station is used to calculate the local model of Tm in Beijing area, then the local model is used to calculate the Tm in 2011. The result shows that the difference mean value is 2. 16 K and the root mean square error is 4. 78. Meanwhile, PWV is calculated by using the local model. Compared with the PWV calculated by the radiosounding data, the resulting that the difference mean value is -1.42 K and the root mean square error is 2.87. The experiment proves the local model of Beijing with high precision and strong practicability. |
