ABSTRACT:
The ground electrostatic field induced by a thundercloud Cumulonimbus (Cb) represented by an electric dipole has been studied. In the process only electrostatic approach has been applied without taking into account time and space changes inside the cloud. However, the position of the entire cloud changes relatively to the observation point. The charge concentrated at the poles of the thunderstorm dipole as well as the altitude of the dipole have been computed from mathematical relations deduced from electrostatic laws. In the process the real conditions - the special dimensions of the cloud and formidable thermodynamic processes inside the cloud - had to be simplified.
