- Аннотация: In July 1994 the pieces of the Shoemaker-Levy 9 comet bombarded Jul,iter. A colossal energy mas released by braking of each comet fragment in the Jovian atmosphere. In the paper we make an attempt to explain the observing data were obtained during the collision of the comet with Jupiter. These are: the burst of radiation on the edge of the Jovian limb during the braking of pieces of the comet in the atmosphere, anomalies in the intensity of the radio frequency radiation of Jupiter in the decameter and decimeter ranges, artificial polar glows in the upper atmosphere of Jupiter. formation and evolution of spots, which are comparable in size with the Great Red Spot of Jupiter. The crucial issues for interpreting the observed data is the depth of penetration of the pieces into the atmosphere of Jupiter and the character of energy release during the braking of a particular fragment. We study the dynamics of destruction and braking of a fragment of the Shoemaker-Levy comet in the atmosphere and then we use these results to interpret the observed data. If a fragment does not penetrate deep into the atmosphere, the nonhomogeneity of the Jovian atmosphere has a determining influence on the propagation of tile shock: wave caused by the explosion of the piece. The upward motion of the shock wave, in the direction of decreasing density, results in the shock wave acceleration. In addition a layer of heated highly-ionized gas is ejected in. the upper Jovian atmosphere, which in our opinion is responsible for a number of the observed phenomena in the ionosphere and magnetosphere of Jupiter. In particular, from this standpoint we can explain the flashes of optical radiation on the edge of the Jovian limb and variations in the intensity of decameter and decimeter radio frequency radiation of Jupiter, which were observed as the fragments entered the atmosphere.
