The paper presents the results of assessing the temporal dynamics of monthly and annual precipitation sums in the Ukrainian Carpathians region, which were based on the use of time series generated on the ClimUAm database. The basis of the database is meteorological observation data for 1946-2020, which were checked for omissions, emissions and climatic homogeneity (homogenization). It is shown that the homogenization process usually leads to the ordering (leveling) of precipitation amounts within the local area of the study region.<\/em>
<\/strong>Multi-year fluctuations in monthly and annual precipitation amounts were approximated by linear trends and 6th degree polynomials. The results obtained were tested for statistical significance using Fisher’s exact test. Monthly precipitation amounts in the region have differences in magnitude and trend signs. Thus, in the winter months, the coefficients of linear trends are insignificant, their sign changes within the region, which indicates the relative stability of precipitation processes in this season. In summer, for the vast majority of stations in the region, trends towards a decrease in precipitation or a slight increase were obtained. Typically, the values of negative coefficients of linear equations are almost an order of magnitude higher. A statistically significant decrease in precipitation was observed in June (Berehove) and August (Pozhyzhevska, Khust, Nyzhniy Studeny, Slavske, Dolyna). In the transitional seasons of the year, trends towards an increase in monthly precipitation amounts were formed. A statistically significant increase in monthly precipitation amounts occurred in March (Yaremche, Dolyna, Kolomyia), but positive trends were obtained for all stations in the region. Positive trends were also obtained in May, and for the stations Mizhhirya, Slavske, Nyzhniy Studeny, and Nyzhniy Vorota they are statistically significant. An increase in precipitation for the entire region was observed in September and October, with statistically significant changes in Uzhhorod, Beregovo, Dolyna (September) and Yaremche (October).<\/em>
<\/strong>Conducting polynomial approximation of time series of precipitation amounts made it possible to identify a conditionally periodic (cyclic) change in the amount of precipitation. The assessment showed a relatively pronounced periodicity in changes in annual and monthly precipitation amounts, which is 40-46 years for both the annual and monthly precipitation time series.<\/em><\/p>\n\n\n\n
