В докладе рассматривается влияние аэрозольных частиц в областях хорошей погоды на глобальную электрическую цепь, когда генераторы электрического поля поддерживающие эту цепь не учитываются, а входят через граничное условие на нижней границе в виде задания величины потенциала ионосферы: φ ∞ .
The paper presents the results of the analysis of variations in the electric field intensity of the surface atmosphere obtained in high-latitude, high-altitude and lowland observation points, together with the parameters of solar and geomagnetic activity.
Changes in the atmospheric electricity characteristics (AECs) during the spring of 2020 in the urban, suburban, and very low human impact areas (Irkutsk, Irkutsk oblast; Voeikovo, Leningrad oblast; Tiksi, Republic of Sakha) are considered. Based on the AEC data, a theoretical assessment of the change in aerosol concentrations at these sites was carried out. Apparently, the decline in economic activity associated with the measures to prevent the expansion of COVID-19 significantly decreased the concentration of airborne particles in cities and suburban regions.
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.
