Abstract: Comprehensive modeling studies of the processes induced in all geospheres by the passage and explosion of the Yushu meteoroid at the Province of Quinghai (the People’s Republic of China) on December 22, 2020 are performed. Thermodynamic and plasma effects, as well as the effects of the plume and turbulence, accompanying the passage of the Yushu meteoroid were estimated. It has been shown that the passage of the celestial body led to the formation of a gas-dust plume. The heated trail of the meteoroid cooled for several hours. Four stages of meteoroid trail cooling are considered. The first of these persisted for ~0.2 s, and the temperature of the trail decreased by a factor of two due to emissions. During the second stage of order of 3 s in duration, cooling due to the trail emissions and expansion took place, and the temperature of the trail decreased by 20 %. In the course of the third stage of order of 6 s in duration, the products of the explosion and the heated gas, thermic, experienced an ~30 m/s2 acceleration and attained 140 m/s speed of uplifting, and the temperature decreased by ~10 percents. The fourth stage persisted for ~50 s, during which the thermic absorbed the cool air at an intensive rate and gradually cooled off and decelerated. The maximum altitude of the uplifting of the thermic reached ~7...8 km. The products of the explosion, contained in the thermic, specks of dust and aerosols, further took part in the following three processes: a slow precipitation to the surface of the Earth, turbulent mixing with the ambient air, and the transport by the predominant winds around the globe. The effect of turbulence in the trail has been shown to be well-pronounced, while the effect of magnetic turbulence has been shown to be almost absent. The following basic parameters of the plasma in the trail have been estimated: the height dependences of the electron densities per unit length and per unit volume, their relaxation times, the particle collision frequencies, the plasma specific conductivities, and the electron temperature relaxation time. At the initial moment, the linear and volume electron densities in the trail have been shown to be equal to about 1019...4 * 1022 m–1 and 1017... 1021 m–3, respectively, and the plasma specific conductivity to be equal to ~103 Ohm–1m–1. The role of the dusty plasma component is discussed. |
