Abstract: The invention relates to a method for dispersing fog and/or clouds. The aim of the invention is to develop a method, by means of which the dispersion of fog and/or the generation of precipitation from clouds may be rapidly and efficiently carried out in an environmentally-friendly manner. Said aim is achieved, whereby ice particles (solid H2O) are applied to the fog and/or the cloud with an initial speed of between ca 10 m/s and ca. 300 m/s, preferably between ca 100 m/s and ca. 200 m/s, whereby the ON particle size is chosen to be larger than the droplet size, thus causing dispersion of the fog and/or a precipitation from the cloud.
