Time series of multiyear average temperature, obtained at 927 Northern Hemisphere weather stations for the period 1955–2014, are compared with the known data on astronomical insolation for the same time interval and location. It is shown that the annually averaged astronomical insolation as a function of latitude, subject to linear transformation, should be considered as the average latitudinal temperature. This result is justified using a regression of the compared data and by grouping meteorological stations. Our estimates of the increment of the average latitudinal temperature in the period 1985–2014 as compared with those in 1955–1984, as well as the contribution to the temperature variations from the components determined by astronomical insolation and by stochastic processes in the geosphere, do not contradict the well-known estimates, which verifies the introduced linear transformation of astronomical insolation.
