For the first time, the changes in the atmospheric electric field (E_z) during foggy conditions is studied in a hyper-arid region; the United Arab Emirates (UAE), using comprehensive measurements during the Wind-blown Sand Experiment (WISE)-UAE. The longer the fog persists, the more variable E_z becomes, primarily due to the fog’s ability to absorb and redistribute the charges of the atmospheric small ions. This absorption alters the ion balance, affecting electrical conductivity within the atmosphere, which in turn leads to sustained alterations in E_z. A record high E_z value of 2571 V m⁻¹ was measured during a long-lasting fog event. E_z values returned to normal during the fog dissipation phase. The results of this work can be applied to develop techniques for fog harvesting and to improve fog forecasting by accounting for the effect of the electric field on fog lifetime and characteristics.

首次在极度干旱地区研究了雾条件下大气电场（E _{z ）的变化；}阿拉伯联合酋长国 (UAE)，在风吹沙实验 (WISE)-UAE期间使用综合测量。雾持续的时间越长，E _{z 的}变化就越大，这主要是由于雾吸收和重新分配大气小离子电荷的能力。这种吸收改变了离子平衡，影响了大气中的电导率，进而导致 E _z的持续变化。在一次持续的雾气事件中测量到了创纪录的高 E _z值 2571 V m ^{-1 。}在雾消散阶段，E _{z值恢复正常。}这项工作的结果可用于开发雾收集技术，并通过考虑电场对雾寿命和特性的影响来改进雾预报。
