Propagation of a cold wave in the snow during the preparation of ski slopes by salting

The paper presents a method of hydrological and hydrophysical studies to observe the propagation cold wave in snow during preparation ski slopes by salting. Salting is used for competitions, especially when average daily air temperature approaching positive levels, day there melting cover, short-term decrease column its partial freezing. experiments were carried out summer 2021 2022 on Dzhanquat Garabashi glaciers Caucasus. thermal sensors logger manufactured LLC "MSU-Geophysics". located rod stuck with an interval 5 cm. was measured every minute. With single salting, observed about 4-5 hours freezing lower strata underlying layers -3--5 °C.The analysis observational data showed deep into 50-60 research will allow us investigate peculiarities salting optimize process most effective competitions.
