【 摘 要 】

Series of temperatures measured at 818 weather stations in the Northern Hemisphere and one series of Wolf numbers for the period from 1955 to 2010 are considered. The sun's effect on the surface temperature is estimated by the cosine of the angle between two vectors determined by the series under study for the same months, year by year in the observation interval. The sun's effect is distributed over the weather stations, both in space and time. It has a quasi-monotonic dependence on the average monthly temperature, and reflects the geography of the climate, including the effect of warm ocean currents. Various manifestations of the sun's effect on the surface temperature have been discovered, and the conditions of their occurrence are discussed. The approach proposed in this paper can be used in observational data analysis, analytical transformations, and climate simulations.
