The average differences between the seasonal precipitation for meteorological seasons and those of thermal and calendar seasons in 1951–2020 [mm]

meteorological seasonvs. thermalvs. calendar
winter+10−10
spring− 5+ a dozen to several dozen
summer− 1 to −5- several to − 20-odd
autumn− 4- a dozen to − 20

The average differences between the temperatures of meteorological seasons and those of thermal and calendar seasons in 1951–2020 [°C]

meteorological seasonvs. thermalvs. calendar
winter+0.1 (West) to +0.4 (East)+0.3 whole area
spring+1.0 (West) to +2.5 (East)+3–3.5 whole area
summer+0.2 whole area−0.5 whole area
autumn−0.2 to −0.4 depending on the region−3.0 whole area

The coincidence of the beginning of the meteorological and thermal seasons, with up to five days’ variation (the number of occurrences between 1951 and 2020)
