abstract = "In recent decades, the response of surface meteorology to the variation of the B y component of the interplanetary magnetic field (IMF) at high latitudes, known as the Mansurov effect, has been extensively studied. However, the role of the global electric circuit (GEC) in these processes is still unclear. Recent studies suggested that the response of cloud microphysics to IMF B y -induced changes in cross-polar cap potential and fair weather downward current density J z may be one of the possible ways for solar wind-surface meteorology coupling. Such a mechanism requires confirmation, but numerical studies that would show the Mansurov effect discovered in observations have not been carried out earlier. In this work, we evaluated a sensitivity of surface meteorological parameters to a certain change in the stratiform-cloud autoconversion rate imposed by the IMF B y -related changes in the J z using the chemistry-climate model SOCOLv3. It should be noted that in this first study, we use the non-realistic approach where the IMF B y -induced anomalies staying constant for the whole period of simulation. Nevertheless, we found that even small changes of ± 12% in the J z and corresponding changes in the autoconversion rate in regions where IMF B y -induced anomalies in the cross-polar cap potential occur, can lead to large-scale anomalies in surface pressure (up to 2 hPa) and air temperature (up to 1.5∘ K) at high and middle latitudes that are in good agreement in magnitude with those detected in observations. This study shows the importance of further investigating solar-terrestrial coupling through the GEC using global climate models.",
