The paper presents the field observation data on variations in the pressure and electric field intensity in the near-surface atmospheric layer during the passage of the morning solar terminator in several regions of the Russian Federation: on Kamchatka, Kola Peninsula, and in Vladimir oblast. Analysis of the data shows that the pressure and electric field intensity undergo synchronous variations during the passage of the solar terminator. An isolated series of events has a mutual correlation coefficient of variations in the pressure and electric field intensity in the period of passage of the solar terminator that exceeded 0.9 with a subsequent decrease to the background values of ≈0.2–0.3.
