“…[19][20][21]). The construction of hard sphere models of direct three-body recombination of ions (3) in the works [31,32] and of bimolecular recombination of ions (4) in the present paper allows one to suppose that hard sphere concepts can be used while describing such complicated recombination processes as ion-ion recombination reactions in the atmosphere [69,70], the death of oxygen atoms in the atmosphere due to recombination with the participation of O 2 and N 2 molecules as the third bodies [71], or recombination of radicals in the polymer cage and in the bulk of polymers [72]. FUNDING This work was carried out within the framework of the Program of fundamental scientific research of the state academies of sciences, the theme being "Fundamental physicochemical processes of the impact of energy objects on the environment and living systems".…”

We propose a hard sphere model of bimolecular recombination RM+ + X– → MX + R, where M+ is an alkali ion, X– is a halide ion, and R is a neutral rare gas or mercury atom. Calculations are carried out for M+ = Cs+, X– = Br–, R = Ar, Kr, Xe, Hg, for collision energies in the range from 1 to 10 eV, and for distributions of the RM+ complex internal energy corresponding to temperatures of 500, 1000, and 2000 K. The excitation functions and opacity functions of bimolecular recombination in the hard sphere approximation are found, and the classification of the collisions according to the sequences of pairwise encounters of the particles is considered. In more than half of all the cases, recombination occurs due to a single impact of the Br– ion with the R atom. For the recombination XeCs+ + Br–, the hard sphere model enables one to reproduce the most important characteristics of the collision energy dependence of the recombination probability obtained within the framework of quasiclassical trajectory calculations.

“…The reaction of the thermosphere and ionosphere parameters to these events reveals, particularly, in the formation of ionospheric irregularities over the region of disturbances in the lower atmosphere, the appearance of traveling ionospheric disturbances, disturbances in electric fields, optical emissions, F-expansion phenomena, etc. [24,[30][31][32][33][34][35][36][37]. These phenomena in the thermosphere and ionosphere develop relatively quickly, i.e., within a few hours after the occurrence of disturbances near the Earth's surface [1,5,6,38,39].…”

Disturbances of the Thermosphere and the Ionosphere during a Meteorological Storm

Determination of the physical mechanisms of energy transfer of tropospheric disturbances to the ionosphere is one of the fundamental problems of atmospheric physics. This article presents the results of observations carried out using two-wavelength lidar sensing at tropospheric altitudes and satellite GPS measurements during a meteorological storm in Kaliningrad (Russia, 54.7° N, 20.5° E) on 1 April 2016. During lidar sensing, it was found that the amplitudes of variations in atmospheric parameters with periods of acoustic (AWs) and internal gravity (IGWs) waves significantly increased. As a result of numerical modeling using the AtmoSym software package, it was shown that there is a noticeable increase in the period of temperature disturbances from 6–12 min to 10–17 min at altitudes from 150 km up to 230 km during the vertical propagation of acoustic waves and internal gravity waves from the troposphere. Nonlinear and dissipative processes in this layer lead to the formation of sources of secondary waves in the thermosphere with periods longer than those of primary ones. In this case, the unsteady nature of the wave source and the short duration of its operation does not lead to significant heating of the thermosphere. Simultaneous satellite observations demonstrate the response of the ionosphere (total electron content (TEC) disturbance) to tropospheric disturbances. Analysis of the time series of the amplitudes of the reflected lidar signal and TEC made it possible to determine that the response time of the ionosphere to tropospheric disturbances is 30–40 min.
