Results of ground‐based measurements of the atmospheric electricity parameters at the network of middle‐ and high‐latitude observatories are used for the investigation of the space‐time structure of regular and irregular variations of the atmospheric electricity of fair weather Regular diurnal variations contain a complex superposition of universal, local, and magnetic local time controlled variations. Amplitudes of these components depend on season, latitude, and height of an observatory above the sea level. Subdivision of the irregular atmospheric electricity variations, in accordance with their space and time structure and physical nature, helps to extract the particularities of atmospheric electricity responses to the different geophysical events, such as the complex of global phenomena joined by the term “geoeffective solar flare” and inclusive solar proton events, Forbush decreases of galactic cosmic ray fluxes and planetary magnetic storms; and regional phenomena in atmospheric electricity conditioned by magnetospheric substorms in high latitudes and by the Chernobyl (Ukraine) nuclear accident (1986) in Eastern Europe.
The dynamics of the anthropogenic atmospheric pollution level is evaluated using atmospheric electrical data obtained at a network of stations. These stations are distributed at midlatitude plain and mountain stations and also at two high‐latitude stations on the Kola Peninsula. The anthropogenic atmospheric pollution level is estimated from a comparison of atmospheric electricity data measured on weekdays with data measured on Sundays, when work‐related pollution activities are reduced.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
