Abstract: 
We present a comprehensive modeling study of the processes induced in all geospheres by the passage and explosion of a representative meteoroid. As an example, we analyze the event that occurred over Romania on January 7, 2015. The modeling allows estimating of mechanical, optical, gas-dynamical, and thermal effects associated with the passage of the Romanian meteoroid. The major release of energy (1012 J) is shown to occur at approximately 44 km altitude where the rate of mass loss and the optical radiation power have reached approximately 14.5 t/s and 1 TW respectively. The pressure at the shock at the epicenter of the meteoroid explosion was equal to several dozen pascals. The passage of the cosmic body led to the formation of a gas-dust plume. The hot trace from the meteoroid was cooling down for a few seconds.
Keywords: gas-dust plume, gas-dynamic and thermal effects, interaction with atmosphere, mechanical, meteoroid, optical
