From the data of observations at 43 aerodromes in European Russia and the neighboring countries for 2001-2018, linear trends are calculated of temperature, humidity, and pressure, and then compared against the temporal changes in pressure field patterns. The latter are estimated on the basis of objective analysis data, using a special software. The linear trends show that the trends of annual-mean and season-mean temperature are positive practically at all the sites, though mean temperature in separate months can exhibit both decrease (in January) and strong increase (in December and summer months). The annual mean dew-point deficit increases in time almost everywhere, while surface pressure increases in the north (larger) part of the area and decreases in its south part. It is shown also, by means of objective classification of pressure field patterns, that the growth of cyclonic situations occurrence frequency dominates in the south part of the area, and the growth of anticyclonic situations occurrence frequency dominates in its main, north part. This result is consistent with the pressure trends distribution over the area.
