- Аннотация: Using a model of the general circulation, the response of the temperature and wind in the Earth's atmosphere to variations in solar UV radiation flows during an 11-year activity cycle is studied with respect to their dependence on the wavelength. Satellite measurement data for the 23rd cycle that were characterized by anomalously low flows of UV radiation at minimum activity are used in calculations. To implement numerical scenarios, wavelength-dependent variations in the UV radiation flow changing absorption in the bands of ozone and molecular oxygen are used in the radiation block of the model. Based on empirical data, a spatial structure of stationary disturbances having the wavenumbers S = 1, 2, and 3 are assigned at the lower boundary of the model. The calculation results demonstrating the changes in the atmospheric parameters between the solar activity maximum and minimum within the height range 0-120 km are presented. It is shown that the response of monthly average values has a wavy structure in latitude, i.e., a nonseasonal character, amounting to several degrees in the lower atmosphere. The results obtained indicate that planetary waves are an important link in the transmission of an external effect on the lower atmosphere.
