When the 2013 meteor entered into the Earth's atmosphere with an energy release equivalent to 100 or more kilotons of TNT, dozens of times more powerful than the atomic bomb dropped on Hiroshima, the meteor's shock wave produced damage as in a supersonic jet's flyby (directly underneath the meteor's path) and as a detonation wave, with the ...

2018年8月1日 · Shock waves and the associated phenomena generated by strongly ablating meteoroids with sizes greater than a few millimeters in the lower transitional flow regime of the Earth’s atmosphere are the least explored aspect of meteor science.

2025年1月23日 · Larger meteors entering the atmosphere create shock waves which can be detected on the ground as low-frequency vibration known as infrasound. Shock waves result when the matter through which the wave is passing is …

2018年8月1日 · Shock waves are generated by almost all strongly ablating and sufficiently large meteoroids that enter denser regions of the Earth’s atmosphere and reach the lower transitional flow regime as defined by the Knudsen number (provided that these meteoroids retain sufficient mass and velocity close to that of the initial pre-atmospheric velocity).

Shock waves and the associated phenomena generated by strongly ablating meteoroids with sizes greater than a few millimeters in the lower transitional flow regime of the Earth’s atmosphere are the least explored

2024年6月11日 · The paper presents the results of studies of shock waves propagating in the atmosphere. These results were obtained by recording sound waves generated by a shock wave. It has been shown that it takes approximately two seconds for a shock wave to form.

Most traditional models for the propagation of shock waves in the open atmosphere assume an isotropic and homogeneous atmosphere ([1],[2]) but their results may diverge significantly especially when the overpressure is small (Figure 1).

2008年5月1日 · The present report is aimed at a comparison of waveforms and spectra of laser-induced acoustic shock waves generated by single liquid and solid aerosol particles, monodisperse liquid and solid aerosol particle ensembles, and outdoor atmospheric aerosol and elucidation of their special features.

2020年2月15日 · This Special Issue is focused on shock waves and their effects on planetary atmospheres, including shock wave generation, propagation and attenuation, as well as source localization and characterization.

In a shock wave, the properties of the fluid such as density, pressure, and temperature change almost instantaneously. The energy of a shock wave dissipates relatively quickly with distance. Many types of shock waves are found in astrophysical environments.
