以大雾天气为例，利用WRF中尺度数值预报模式对各物理参数进行调整，从而验证各物理方案对大雾形成和发展的作用，并将其与控制性实验进行比较。对水汽通量散度、雾区范围分析，结果表明：这三个敏感性实验都不能很好地反映实况，因此原控制性实验更适合做定量定性研究。%Taking foggy weather as examples, this paper uses the numeric scale WRF forecast to make an adjustment on the physical parameters for the purpose of verification and validation to different physical plans which form and develop fog. And the controlled experiments are compared which include the vapor flux divergence and mist areas. The results indicate that all the three sensitivity experiments can not well reflect the realities. Therefore, the original controlled experiment is more suitable for auantitative and qualitative study.
