DETERMINATION OF CLOUD ELECTRICAL STRUCTURE BY THE SINGLE-VALUE DECOMPOSITION METHOD

The problem of determining the electrical structure of clouds is consi dered. This is an inverse task because it requires an evaluation of th e electrical charge distribution in the cloud as well as the charge bo undaries. The problem is solved on the basis of a model with the essen tial characteristics of a real electrified cloud. A space model of a c loud with vertical charge distribution is used. An analysis of differe nt methods of solution and their influence on errors is given. It is s hown that the single-value decomposition method is the most effective. This method makes it possible to analyse the limits of specification of the electrical structure of a cloud with the aid of the model adopt ed.
