Abstract
The presented work is devoted to establishing the features of spatial and temporal distribution of cases of mass deposition of ice on the territory of Ukraine during some decades 1991-2000, 2001-2010, 2011-2020. The number of such cases by individual months and years of the studied periods and their maximum value were determined. It was found that the largest number of cases of mass spread of ice deposits with more than 20 stations in some decades was up to 5-7 in 1991-2000 and 2001-2010 and 8-12 in 2011-2020, especially in January, November and December . The largest number of cases of mass spread of ice deposits of 30 or more stations on 1 date was 4-5 days, but more often 2-3 days. The duration of periods of mass distribution of ice deposits during the studied decades was mostly 2-3 days, but in some months it can increase to 4-6 days. This is more noticeable in 2001-2010 and 2011-2020. In general, taking into account all cases of mass deposition of ice, they are most often observed in the central (Vinnytsia, Cherkasy, Kirovohrad, Dnipropetrovsk), northern (Kyiv, Chernihiv), northeastern (Kharkiv), eastern (Donetsk) and some southern (Odessa, Kherson) regions. Territorially, cases of mass deposition of ice with more than 30 stations on the 1st date are spread in the areas of the north, northwest, northeast, east and center of the country. In some cases, they are joined by some southern regions – Odessa, Mykolaiv, Kherson. Among the western regions are Volyn, Lviv, Khmelnytsky and Ternopil regions.
