Three-dimensional simulation of changes in temperature, wind and the earth’s atmosphere chemical composition caused by solar activity

Results of three-dimensional numerical simulation of changes in temperature and wind at heights up to 130 km caused by changes in extremely low solar UV radiation fluxes in the 23 r cycle as well as by ozone destruction in polar regions by high-energy particles of a space origin. The response of temperature to UV radiation variations was shown to have an essentially non-zonal character caused by the existence of quasistationary wave sources in the model. Besides, the visible effect (of several K) appears at tropospheric levels. On an example of October-November, 2003 events, the photochemical simulation of energetic particle influence on the polar atmosphere showed the long-term effect of ozone destruction area caused by lowering of the area of higher content of nitrogen oxides that results in stratospheric temperature changes after polar night.
