The influence of the electric field on the ice-forming properties of the reagent in the implementation of various mechanisms of crystallization

Abstract

Abstract The features of the formation of ice crystals on reagent particles in a cloudy medium in the presence and absence of an electric field have been studied in the work. A complex of equipment from the laboratory of cloud microphysics of the High-mountain Geophysical Institute, which includes a sublimation chamber, a small cloud chamber, and an installation for bubbling reagent particles, was used. As a result of the experiments, it was found that when the condensation-crystallization mechanism is implemented, the specific yield of ice-forming nuclei in the cloud chamber decreases with increasing electric field intensity. When implementing the immersion mechanism, the electric field does not affect the specific output of ice-forming nuclei. In the case of a contact mechanism, the specific output of ice-forming nuclei is 2–3 orders of magnitude smaller than with the realization of the condensation-crystallization and immersion mechanisms.
