Abstract
Features of the change in the specific irradiation energy and irradiation intensity in the latitudinal zones of the Earth during the phase of decreasing axial tilt (in the interval from 3000 BC to 2999 AD) have been determined. Variations in the annual specific irradiation energy and irradiation intensity are similar in character, which reflects the increase in latitudinal contrast in the annual irradiation of the Earth. The specific irradiation energy decreases in the summer half-years and increases in the winter half-years (seasonal differences are smoothed out). The irradiation intensity exhibits a more complex pattern, in which seasonal differences in the Northern Hemisphere are smoothed out more noticeably than in the Southern Hemisphere. In the phase of decreasing angle of inclination, the area of the regions located beyond the polar circles decreases by approximately 25.93%, the regions between the tropics and the polar circles increases by 12.87%, and the regions between the tropics and the equator decreases by 9.80%.
