摘要

Dust particle electrization in arid environments plays a crucial role in atmospheric dynamics, influencing local electric fields and generating electromagnetic activity. This study investigates the low atmospheric electrical and electromagnetic properties of dust-laden arid Kalmykia regions under moderate wind conditions and convective dust aerosol transport. Comprehensive multilevel measurements of wind speed, temperature, humidity, solar radiation, and electric potential were conducted alongside the Dust Complex instrumentation, which includes piezoelectric sensors and an Electromagnetic Analyzer (EMA). The analysis reveals a strong correlation between soliton electromagnetic bursts, and fluctuations in electric field strength and wind speed. A significant increase in burst frequency and intensity was observed under low relative humidity conditions (< 30%), highlighting its role in enhancing discharge activity. The shift in the relationship between electric field strength and relative humidity suggests that charge formation is driven by the balloelectric effect. Statistical and cross-correlation analyses further indicate lagged effects of temperature variations on electromagnetic activity, emphasizing the complex relation between thermal and mechanical processes in dust electrization. These findings provide valuable insights into dust charging and discharging mechanisms in arid environments, with implications for understanding similar phenomena in planetary atmospheres, particularly on Mars, and it is in this context that the results obtained are discussed. The study underscores the importance of integrating high-frequency electromagnetic measurements with meteorological data to refine models of dust dynamics and atmospheric electrization.
