Abstract
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.
利用ERA5再分析资料，研究了1979-2018年伏尔加河联邦区西北部0.25×0.25°空间分辨率热态的时空变化。为了研究气温的高度分布，在地面至47 km (1 hPa)的37个等压面上构建了线性温度趋势的平均值、标准差和斜率系数的垂直剖面图。并计算了决定系数。确定了温度场中对流层-平流层相邻水平之间按季节和全年总体的相关程度，揭示了对流层顶区域的显著减弱。揭示了对流层低层温度上升和平流层温度下降的时间趋势。
