The most spectacular fulmini are those that occur between the temporal nuclei and the suolo, however there are instances where a fulmine occurs between two nuclei or inside the same nucleus. When the fulmine does not scarify the soil, one may speak about saette. The phenomenon that results in the formation of a fulmine occurs when the nuclei of the stars are charged electrically and begin to gonfi due to the convective movements of the wind and the moisture that escapes from the suolo.
