As part of the research topic “Forecasting the variability of climate-vulnerable areas in Ukraine in the coming decades” (state registration number 0118U000554) a study of spatio-temporal distribution of ice category (dangerous) and SHP (spontaneous) was conducted in Ukraine at the present stage of climate change. The purpose of this article is to study the distribution of ice deposits of large diameters, namely dangerous (DHP) and spontaneous (SHP) in Ukraine during the current stage of climate change. It was also necessary to summarize the information on the identifi ed losses and their nature from ice deposits of the spontaneous (SHP) category, registered in some regions of Ukraine during this time. Main material. Dangerous ice deposits of the category are quite common in Ukraine and are observed almost every year. They are most common in the winter months (December-February) and in late autumn in November, when they are found in at least half of the regions. During 2011-2019, they were territorially observed in most oblasts, especially in the western, central and eastern regions. In the south, such deposits were mostly observed in Odesa, Mykolaiv, Kherson oblasts and the Autonomous Republic of Crimea. In April, such deposits were observed only in the Carpathian region of Transcarpathia in Playa. During October 2011-2019, dangerous ice deposits were found only in the Carpathian region (Zakarpatska and Ivano-Frankivsk regions), in some places in the center (Kirovohrad and Dnipropetrovsk regions) and in the south (Odessa, Mykolaiv, Kherson regions). Spontaneous ice deposition is observed in the territory not every month and year, but more o???? en in the cold period. The areas where they occur most o???? en are highlighted, namely in Transcarpathia at the Play weather station. However, there are places where such deposits also occurred quite often in the study period - in Lviv region (Kamyanka-Buzka, Rava-Ruska), Zhytomyr region (Olevsk, Zhytomyr), Mykolayiv region (Mykolayiv, Ochakiv), Donetsk region (Amvrosiyivka, Mariupol), Zaporizhzhia region (Zaporizhzhia, Huliaipole), the Autonomous Republic of Crimea (Chornomorske, Opasne, Simferopol). Damage from ice deposits of the SHP category was observed in 4 years out of 9 studied at the facilities of the industrial complex, transport and utilities. The largest number of losses was recorded in 2014. Conclusions. It was found that the most common dangerous ice deposits during 2011-2019 were in January, February, December, where they were observed in 10 to 14 regions, and especially in March in 21 region. They were most common in the western, central and eastern regions, and in the south in Odessa, Mykolaiv, Kherson regions and the Autonomous Republic of Crimea. Ice deposits of a spontaneous nature were mostly observed in the Zakarpatia region in Playa, as well as at some meteorological stations in Lviv, Zhytomyr, Mykolaiv, Donetsk, and Zaporizhzhia regions.
