Abstract

We studied the possibility to apply the ionospheric electric potential (EP) as a parameter describing the effects of solar activity on the troposphere. EP was calculated using the semi-empirical model where the potential spatial distribution is determined by solar wind and interplanetary magnetic field parameters, and AL index of geomagnetic activity for 1975– 2019. It has been shown that EP can be used as an indicator of solar activity to study correlation of long-term EP variations and tropospheric parameters. The revealed similar trends in long-term EP and near-surface temperature variations suggest that the changes in climate system parameters are induced by slower changes in large-scale magnetic field of the Sun. The performed analysis of EP and near-surface temperature correlation maps revealed that natural tropospheric conditions impose their influence on spatial distribution of tropospheric response to solar impact.
