The article is devoted to the study of spatio-temporal distribution of DP (dangerous phenomena) frost deposits on the territory of Ukraine during the last 30 years, which characterize the current state and dynamics of the climate system in Ukraine and its individual elements. The aim of the study was to establish the features of spatio-temporal distribution of such sediments in the regions of Ukraine for individual decades of the study period and to outline the trend in their distribution. some increase in the incidence of such deposits in some months of the transition seasons. For the last decade, there has been an increase in such cases in January and December compared to previous decades. However, during the last 2 years the number of cases of frost deposits of the DP (dangerous phenomena) category has slightly decreased. It is proved that the vast majority of such cases were observed in Transcarpathia at the meteorological station Play, which is associated with a higher frequency of favorable conditions for its formation.Given the results of the study, we can say that in 1991-2000 the largest number of cases of frost deposits of the category of DP in Ukraine was observed in January, February and December, with January accounting for the vast majority of cases.During January, frost deposits of the DP category were quite widely represented on the territory of Ukraine in 9 oblasts. During February and March, they were observed only in mountainous areas – in Transcarpathia and in the Autonomous Republic of Crimea. In April, October and November, such deposits were observed only in Transcarpathia at the Play meteorological station. In December, their range expanded and they were observed not only in the mountains, but also in the north, northeast and east of the country in 5 regions.The largest number of such cases during 1991-2000 was observed in Transcarpathia (Play) and in the Autonomous Republic of Crimea (Ai-Petri).In the period 2001-2010, the main number of cases of frost deposition of the DP (dangerous phenomena) category falls on the months of the cold period of the year, especially January and December. In contrast to the period 1991-2000, the number of cases increased in March and November, and the number of such deposits increased slightly in April.The vast majority of cases of frost deposits of the DP (dangerous phenomena) category during 2001-2010, as well as in the previous decade, were observed in Transcarpathia at the Play weather station.During 2011-2020, there was an increase in the number of cases of DP frost deposits in January and February compared to 2001-2010 and a slight decrease in these deposits in November and December. Also for this period, a greater localization of such sediments in Transcarpathia was established in all the studied months compared to the previous study periods, when especially in January and December such sediments were quite widespread in Ukraine.

TRENDS IN THE SPREAD OF FROST DEPOSITS OF THE CATEGORY DP (DANGEROUS PHENOMENA) ON THE TERRITORY OF UKRAINE DURING THE LAST THIRTY YEARS 1991-2020
