Abstract
A diurnal wave of the ground-level electric field of nonstandard type is regularly observed at the Carpet array of the Baksan Neutrino Observatory of the Institute for Nuclear Research of the Russian Academy of Sciences (43.3° N, 42.7° E) located in a mountain gorge at an altitude of 1.7 km above sea level. In a period of July 29 to September 6, 2019, which included two magnetic storms, it was observed that the diurnal wave of the muon intensity with an energy of more than 100 MeV registered by the array changed its sign. In this period, the diurnal behavior of the pressure, temperature, and ground-level electric field did not change. Using the case of inversion of the diurnal wave, we estimated the contribution of the regularly measured disturbance of the atmospheric electric field to the muon intensity variations. During the study, previously unnoticed morning–evening variations of terrestrial origin were revealed.
