Formulation of the problem. The concept of implementing state policy in the field of climate change until 2030, which aims to develop a national climate program and prevent the reduction of risks associated with them in different regions of Ukraine. The research was performed in accordance with the objectives formulated in the research works of Odessa State Ecological University on the following topics: «Regime of precipitation in the regions of Ukraine in the late XX and early XXI centuries» (№ SR 0111U000590); «Forecasting of dangerous meteorological phenomena over the southern regions of Ukraine» (№ SR 00115U006532); «Comprehensive method of probabilistic and prognostic modeling of extreme hydrological phenomena on the rivers of southern Ukraine to ensure sustainable water use in climate change» (№ SR 0121U010964). Problems of further research. The results presented in the article, of course, can not be considered exhaustive in terms of determining the impact of only two climatic signals that can form the spatial distribution of precipitation in southern Ukraine. The solution of the problems in the future will be directed to the consideration of other known teleconnections of the Northern and Southern Hemispheres with the involvement of additional equidistant empirical data. The purpose. This article aims to identify the features of the spatial distribution of precipitation in the winter season and determine the responses of climatic signals (North Atlantic and North Caspian fluctuations) in their fields in southern Ukraine (Odessa, Mykolaiv, Kherson, Zaporizhia region and the Autonomous Republic of Crimea). Research methods. The implementation of an integrated statistical approach was carried out in three stages with the involvement of methods of multidimensional statistical and cartographic analysis and methods of research of non-stationary random processes. The subject of the study is the series of monthly precipitation for December, January, February at 40 stations in Ukraine and time series of average ...
