It is demonstrated that: on magnetically weakly disturbed/ quiet conditions (Ap < 12) in equinoctial months the red line intensities are minimal, while those of the green line are maximal; the red line intensity increases in May–July and is comparatively low in June, where, unlike most mid-latitude regions, the green line intensity is maximal. The red and green line intensities increase with growing solar activity but their behaviors stay the same, which is considered as a possible regional manifestation of lower and upper atmosphere vertical coupling. It was also detected that, for cloudless nights in June, the number of magnetically disturbed day-nights is maximal and the decrease of the GCRs flux is the biggest during a year. 2013-03-11 published Acta Geophysica 62 2 VERSITA 381-399 DOI: 10.2478/s11600-013-0122-4 TRUE
