Sp. Solovev et Vv. Surkov, ELECTRIC PERTURBATIONS IN THE ATMOSPHERIC SURFACE-LAYER CAUSED BY AN AERIAL SHOCK-WAVE, Combustion, explosion, and shock waves, 30(1), 1994, pp. 117-121
The low-frequency electric field associated with the propagation of an
aerial shock wave in the atmospheric surface layer was studied experi
mentally and theoretically. The experiment involved the recording of v
ariations of the vertical component E(z) of the electric field strengt
h in the atmosphere by means of electrostatic flux meters and rod ante
nnas set up on the surface of the ground. Analysis of the experimental
data shows that electric field perturbations are caused by changes in
the shock wave density of the volume electric charge formed by heavy
ions and aerosol particles. An approximate proportionality is observed
between the amplitude of electric field perturbations, shock wave par
ameters, and concentration of charged particles in the atmospheric ele
ctrode layer.
