The spatial-temporal changes in the thermal regime with a spatial resolution of 0.25×0.25° in the north-west of the Volga Federal District were considered according to the ERA5 reanalysis data for the period 1979-2018 To study the altitude distribution of air temperature, vertical profiles of mean values, standard deviation and slope coefficient of the linear temperature trend were constructed on 37 isobaric surfaces from ground level to 47 km (1 hPa), and the coefficients of determination were calculated. Determined the degree of correlations between adjacent levels the tropo-stratosphere in the temperature field by seasons and in general for the year, its significant weakening in the tropopause region was revealed. The time tendency of temperature rise in the lower troposphere and its decrease in the stratosphere is revealed.
