地基GPS水汽反演昆明地区加权平均温度的模型建立

本文根据长期的气象探空资料通过数值积分的方法算出每个时次的加权平均温度,然后在此基础上对Bevis回归经验公式进行订正;在加权平均温度模型的建立中,计算公式中系数a、b的求解由计算软件根据最小二乘原理快速结算。最后通过相应的数据模拟计算证明这种方法可以确定出适合昆明本地区的加权平均温度计算模型。

Model establishment of weighted average temperature in Kunming area by ground-based GPS water vapor inversion

According to long-term meteorological sounding data,the paper calculated the weighted average temperature of each time by using numerical integration methods,and on this basis,revised the Bevis regression empirical formula.When establishing the weighted average temperature model,the formula coefficients a,b was rapidly computed by a programme based on least square theory.The results of the analog computation by data showed that this method could determine the calculation model of weighted average temperature suitable for Kunming region.
