Features of the electric field of the atmosphere in various weather conditions

Abstract

The article presents data on the measured series of electric field strength in the atmospheric surface layer for the period from 2010 to 2019 using the EFM550 electric field strength meter. The comparability of the influence of local (fogs, precipitation, thunderstorms, etc.) and global (cyclonic processes, solar-terrestrial communications, etc.) factors on atmospheric electric field variations is discussed. Global and local variations in the nature and dynamics of field strength for the conditions of the North Caucasus are confirmed. An analysis is made of the frequencies of the occurrence of a range of surface atmospheric electric field values. The obtained method of processing information about the repeating values of the polar atmosphere and the Earth’s atmosphere. For this purpose, a branch has been compared with a number of actual weather observations in the central part of hydrometeorology and environmental monitoring. Federal State Budgetary Institution “North Caucasus Office for Hydrometeorology and Environmental Monitoring” Roshydromet. The features of the influence of various meteorological phenomena on the state of the electric field strength were statistically described and a study was conducted to assess the influence of local phenomena -precipitation, clouds and thunderstorm activity on the change in the value of the electric field of the atmosphere in the area of the city of Nalchik.

Relationship of precipitation intensity in the form of snow with atmospheric electricity and radiothermal radiation of the snow cover

“…Studies of the atmospheric electric field strength under different weather conditions were performed in [5,6]. For example, variations of the atmospheric electric field strength occur during precipitation.…”
