The Correlation of Temperature, Stratus Cloudiness, and Electric Field Strength in the Atmosphere

This paper presents the results of observations and processing of experimental data on long-term (2012–2018) continuous electric field measurements and compares them with the meteorological parameters. Based on the field observations analyzed, the daily average electric field correlates with the daily average total cloud cover regardless of the season with a correlation coefficient of –0.48, while the correlation coefficients between the average electric field and temperature vary from –0.39 in winter to 0.41 in summer. Theoretical estimates of the stratus cloudiness effect on the electric field in the surface layer confirm a decrease in the daily average electric field strength to 70% in fair weather field.
