Abstract: The invention describes a method of monitoring of increased risk of lightning on the basis of information about the increase of electric charge of water droplets, which are obtained by measuring the characteristics of scattered EM radiation. The change of these characteristics is related to the electric charge, which the droplets acquire. In order to normalize the optical characteristics as well as the concentration of droplets it is necessary that the measurements are carried out at two suitably selected wavelengths. The wavelengths can be combined, allowing the use of two or more wavelengths.
