摘要

We present a brief analysis of the results obtained by studying all known atmospheric photochemical systems with nontrivial nonlinear dynamical properties. In particular, it is demonstrated that multistability and self-oscillations can exist in the photochemical system of the atmospheric boundary layer and lead to a high sensitivity of the concentration of near-surface ozone to emissions of pollutants. Nontrivial properties discovered in the chemistry of the polar lower stratosphere play a key role in the stratosphere dynamics. These properties apparently led to the formation of the Antarctic ozone hole in the mid-1980s. It is shown that in the mesopause region (altitudes of 80–90 km), a nonlinear response of the mesospheric photochemistry to diurnal variations of the solar illumination is possible with the appearance of subharmonic or chaotic oscillations of concentrations of the trace species. Furthermore, formation of nonlinear waves of the reactiondiffusion type can be caused by the influence of the transport processes (in particular, turbulent diffusion), which is a new phenomenon for the Earth’s atmosphere.
