Spatiotemporal distribution of heavy and extreme snowfalls in the Transcarpathian region

Abstract

This paper presents a spatiotemporal analysis of the dynamics of heavy and extreme snowfalls in the Transcarpathian region during 1990-2019. Data on snowfalls are obtained from the observation points of the state hydrometeorological network of the Transcarpathian Regional Center of Hydrometeorology. Also there are data included from the Pozhezhevska snow avalanche station (Ivano-Frankivsk region) as a representative observation point for the highland zone of the eastern part of the Transcarpathian region. The analysis took into account the date of snowfall, the amount of precipitation that fell during the snowfall,l and its duration. The recurrence of different indicators of snowfall distribution was calculated for each observation point separately for the specified thirty-year period. Some results were mapped by the isolines using kriging interpolation. Spatio-temporal heterogeneities and regularities in the distribution of heavy and extreme snowfalls have been revealed.
