Simultaneous measurements of the vertical magnetic field (VMF), three-dimensional electric field, ambient temperature, ambient relative humidity, particle mass concentration, and three-dimensional velocity are conducted during dust, haze, rain, snow, and thunderstorms. The hourly VMF variation (the rate of VMF increment and time increment with a 1-h time interval) is used to evaluate the disturbance level of the atmospheric magnetic field during the abovementioned weather conditions. There is no significant difference in the hourly VMF variations between hazy days and fair weather. However, the hourly VMF variations on dusty, rainy, snowy, and thunderstorm days differ from those in fair weather, implying that these weather conditions significantly affect the atmospheric magnetic field. On hazy days, although the haze particles are charged, the VMF does not change compared with in fair weather, which suggests that the horizontal electric field generated by haze particles is an irrotational field. On dusty and snowy days, the heterogeneity of the charge distribution forms a rotational horizontal electric field, which can induce the VMF to disturb the atmospheric magnetic field. During rain and thunderstorms, the hourly variation in the VMF is larger than in dust and snow, which can be attributed to the rotational horizontal electric field generated by raindrops and clouds. In addition, the hourly variation in the VMF in thunderstorms is one order of magnitude larger than that during days without thunderstorms, indicating that the VMF induced by the cumulonimbus cloud electric field is more significant than that in other weather conditions.

在粉尘，霾，雨，雪和雷暴天气中，同时测量垂直磁场（VMF），三维电场，环境温度，环境相对湿度，颗粒质量浓度和三维速度。VMF的每小时变化（VMF的增加速率和时间间隔为1小时的时间增量）用于评估在上述天气条件下大气磁场的干扰水平。朦胧的天气和晴朗的天气之间，VMF的每小时变化没有显着差异。但是，在多尘，下雨，下雪和雷暴天气，VMF的小时变化与晴天相比有所不同，这意味着这些天气状况会显着影响大气磁场。在朦胧的日子里，尽管烟雾颗粒带电，与晴天相比，VMF不会改变，这表明雾霾粒子产生的水平电场是非旋转场。在多尘和下雪天，电荷分布的不均匀性会形成旋转的水平电场，这会引起VMF干扰大气磁场。在下雨和雷暴期间，VMF的小时变化大于尘土和雪中的变化，这可以归因于雨滴和云层产生的旋转水平电场。此外，雷暴时VMF的小时变化比没有雷暴时的VMF的小时变化大一个数量级，这表明积雨云电场感应的VMF比其他天气条件下的VMF更为显着。这表明由雾状颗粒产生的水平电场是非旋转场。在多尘和下雪天，电荷分布的不均匀性会形成旋转的水平电场，这会引起VMF干扰大气磁场。在下雨和雷暴期间，VMF的小时变化大于尘土和雪中的变化，这可以归因于雨滴和云层产生的旋转水平电场。此外，雷暴时VMF的小时变化比没有雷暴时的VMF的小时变化大一个数量级，这表明积雨云电场感应的VMF比其他天气条件下的VMF更为显着。这表明由雾状颗粒产生的水平电场是非旋转场。在多尘和下雪天，电荷分布的不均匀性会形成旋转的水平电场，这会引起VMF干扰大气磁场。在下雨和雷暴期间，VMF的小时变化大于尘土和雪中的变化，这可以归因于雨滴和云层产生的旋转水平电场。此外，雷暴时VMF的小时变化比没有雷暴时的VMF的小时变化大一个数量级，这表明积雨云电场感应的VMF比其他天气条件下的VMF更为显着。
