Surface atmospheric electric field variability on the Qinghai-Tibet Plateau

The variability in the atmospheric electric field needs to be understood before considering the properties of the atmospheric electrostatic distribution on the Tibetan Plateau. The relationship between each meteorological parameter and the atmospheric electric field should be carefully considered. In this article, atmospheric electric field observations and their effects from weather conditions at Gar Station (80.13 degrees E, 32.52 degrees N, altitude 4259 m) for the period from November 2021 to October 2022 are presented. After defining strict and reliable criteria for fair weather, the authors show the diurnal variation curve of the average fair weather atmospheric electric field, which has double peaks and double valleys. How various meteorological conditions affect variability in the atmospheric electric field and comparisons between the Gar curve and Carnegie curves are also revealed.
