| Zusammenfassung |
| Some years ago, a model of the generation of local electric fields in the atmosphere a few
days before earthquakes and up to a few hours after the seismic shock was proposed. The
generation of the electric fields occurs because of an increased ionisation intensity of the
atmosphere at the presense of aerosols. The generation of the electric field is the result of the
fact that the larger aerosols which are mainly negatively charged have a larger velocity of
gravitational precipitation than the smaller, mainly positively charged aerosols. The
ionisation in such atmospheric regions is caused by radon, the concentration of which
increases in earthquake preparation regions. The formation of mosaic-likely distributed
regions of electric fields with intensities of 3 -
102 - 105 V/m, and on the other
hand, large aereas with increased electrical conductivity should cause a series of
physical effects which may be studied using earth-based, atmospheric and satellite
observations.
The theoretical analysis of the possible infrared emission spectra showed, that the most
important spectral bands, from which information is obtained on electric fields in the
night-time ionosphere, possess wavelengths in the interval between 7.0 μm and 15.0 μm. A
hypothesis is proposed according to which the infrared emissions are not only connected with
the electron acceleration, but also with the heating of the light ions in the electric field.
Consequently there occur particles the energies of which are situated in the tail of the
energy distribution function. Therefore, their energies are sufficient for the excitation
and emission of quanta of energy, which correspond to the vibrational spectral
bands of the molecules N2O, CH4, CO, CO2, O3, and NO2 of the atmosphere. |
