Concentrations of Be-7 cosmogenic radionuclide in aerosols in connection with geomagnetic storms of CIR/HSSWS origin with atmospheric influences.

We investigate the coupling of concentrations of the cosmogenic radionuclide Be-7 (time series of activity concentration of Be-7 in aerosols evaluated by the corresponding activity in aerosols on a weekly basis at the National Radiation Protection Institute Monitoring Section in Prague) with reliable indicators of various atmospheric processes primarily determined by the solar activity level and space weather conditions influenced by coupling processes between the neutral atmosphere, ionosphere including sporadic E layers, magnetosphere and other geospace environment. We try to contribute to better understanding of the dynamics of these processes by associating them with new catalogue of over two hundred geomagnetic storms initiated by co-rotating Interaction Region (CIR)/High-Speed solar wind Stream (HSSWS) during the years 2016 – 2023. The catalogue CIR/HSSWS allows analysis of geomagnetic storms effects on ionosphere and troposphere which were clearly caused by CIR/HSSWS and or sudden stratospheric warmings or various significant tropospheric events like convection associated with frontal passages over European region. We also compare Be-7 concentrations during periods of strong solar and geomagnetic storms with periods of low solar activity in the longitudinal view in years 1986 – 2023.
