FIELD: meteorology.SUBSTANCE: invention relates to the active influence on atmospheric phenomena and, in particular, to rocket projectiles. Hydrometeorological rocket shell includes a housing with a block of basic stabilizers. Inside the housing there are marching, starting stages of the solid fuel engine and the active reagent gas generator, a temporary device with a counting mechanism for the start time of the active reagent generator. Temporary device is additionally equipped with a counting mechanism for the launch time of the sustainer stage and is configured to install pre-launch times for the sustainer stage and the gas generator of the active reagent before the start. In the charge of solid fuel of the sustainer stage, grooves are made to accommodate the planes of the additional stabilizer of the sustainer stage, made with the possibility of changing their position from folded into unfolded. Starting stage contains a gas generator with a fuel composition with a lack of an oxidizing agent for the speci
