Abstract
Abstract A pyrotechnic formulation for use in weather modification comprising a fuel and an oxidizer and a mixture of a metal iodate and an alkali iodate. Upon combustion metal iodide and alkali iodide are generated as mixtures and complexes which show ice nuclei activity at from -5* C. to -20* C. depending on the molar range of metal iodide to alkali iodide.
