In order to explore the influence of water-vapor correction term on wind speed uncertainty, the actual measured value of wind speed by pitot tube is the research object, Firstly, the uncertainty value of the wind speed value obtained by the simplified model (discarding the water-vapor correction term) is evaluated by GUM method. Then, the MCM evaluates the uncertainty of the wind speed value obtained from the original model (including the water-vapor correction term). Finally, two kinds of the evaluation results obtained by the method are compared in the form of probability distribution graphics, and the numerical analysis is carried out. After the water-vapor correction item is discarded, the fluctuation degree and dispersion degree of the measurement result will be reduced, and the degree of reduction is 1.0988% and 1.0929%, respectively. The degree of volatility is about 25.8513% of the degree of dispersion. The degree of influence on the volatility and dispersion of the measurement result is about 0.2305% and 0.8987% of the measured value of wind speed. In the application, for the occasion of pursuing the accuracy of measured value of wind speed, it is recommended to use the original model to measure the real-time wind speed. For the occasion of the stability of the wind speed measurement result, the GUM method can be used to evaluate the uncertainty of the simplified model.

水汽校正项对风速测量不确定度的影响分析

为了探索水汽校正项对风速不确定度的影响，皮托管实际风速测量值是研究对象，首先，简化模型获得的风速值的不确定度值（丢弃水蒸气校正项）通过GUM方法进行评估。然后，MCM评估从原始模型获得的风速值的不确定性（包括水汽校正项）。最后，以概率分布图的形式比较了该方法获得的两种评估结果，并进行了数值分析。丢弃水蒸气校正项目后，测量结果的波动度和分散度将降低，降低度分别为1.0988％和1.0929％。挥发性程度约为分散程度的25.8513％。对测量结果的挥发性和离散性的影响程度约为风速测量值的0.2305％和0.8987％。在实际应用中，为追求风速测量值的准确性，建议使用原始模型进行实时风速测量。为了确保风速测量结果的稳定性，可以使用GUM方法评估简化模型的不确定性。建议使用原始模型来测量实时风速。为了确保风速测量结果的稳定性，可以使用GUM方法评估简化模型的不确定性。建议使用原始模型测量实时风速。为了确保风速测量结果的稳定性，可以使用GUM方法评估简化模型的不确定性。
