The transition of the cloud, thunderstorm state, accompanied by intensive lightning discharges, to hail occurs as a result of the nucleation and growth of hail nuclei in the drop and grain forms. The vertical extent of the volume where nuclei where are formed on giant particles of micro-impurities in the atmosphere (GPA) is between the isotherms from -2 0C to -15 0C. Ice crystals grow due to sublimation and coagulation with supercooled cloud droplets. In the same volume, between the isotherms of temperatures from -5 0C to -16 0C, discharges occur with the maximum number of lightning strikes at an altitude of -10 0C. Lightning strikes introduce an excess volume charge with an ion concentration of about 1017 cm-3 into the cloud space. Positive lightning strikes introduce positive ions, while negative lightning strikes introduce negative ions. These ions are deposited on the GPA, which have concentrations of about 105 m-3 in pre-hail situations. The negative charge on the GPA, contributing to the nucleation of planar crystal structures on the particle, forms a granular hailstone. The positive charge on the GPA forms filamentous structures that break off, and the fragments, when they come into contact with supercooled large droplets and freeze them, lead to the formation of droplet hailstones. To prevent hail, ground lightning, and the redistribution of precipitation, a method based on the initiation of artificial lightning has been proposed. Methods of initiating artificial lightning are given using: plasma formations resulting from the detonation of 100 mm artillery shells in thunderstorm-hail clouds, a special rocket with a detonating cord, and an anti-hail rocket with a conductive surface. A significant change in the radar reflectivity of a thunderstorm-hail cloud has been observed under the influence of an artificially initiated lightning strike. Based on the results of preliminary experiments on hail prevention, the method of preventing and interrupting hail using "reagent plus artificially initiated lightning" has been proposed. Given the established fact that approximately 10 tons of precipitation are released with each lightning strike, it is possible to redistribute precipitation, prevent ground-based lightning, and more using artificially initiated lightning. In the future, unmanned aerial systems should be used to initiate artificial lightning within thunderstorm clouds, while quadcopters should be used in the vicinity of clouds
