摘要

摘要：本文介绍了20 ~ 200 m大小的石质流星体在地球大气中的破坏、蒸发和减速的计算结果。详细地研究了流星体的凝聚态物质及其蒸气和空气之间的热能和动能的再分配。结果表明，当撞击物的大小为几十米时，汽化物质并没有立即减速，而是沿着轨迹长时间飞行，逐渐向空气中传递能量。因此，大气中的主要能量释放发生在蒸汽射流减速阶段，在流星体及其碎片完全汽化之后。

Energy Release in the Atmosphere Induced by the Impact of Meteoroids 20–200 Meters in Size

Abstract—The results of calculating the destruction, evaporation, and deceleration of stony meteoroids with sizes from 20 to 200 m in the Earth’s atmosphere are presented. The redistribution of thermal and kinetic energy between the condensed matter of the meteoroid, its vapors, and air is studied in detail. It is shown that when the size of the impactor is several tens of meters, the vaporized matter is not decelerated immediately, but flies along the trajectory for a long time, gradually transferring energy to the air. As a result, the main energy release in the atmosphere occurs at the stage of vapor jet deceleration, after the meteoroid and its fragments have completely vaporized.
