We present the results of spatial distribution of moisture content in the Mediterranean-Black Sea region during the warm and cold seasons. We analyze moisture content in the layers of the troposphere with the largest % of moisture flow in the cold and warm seasons. We calculate the moisture content in the Mediterranean-Black in the 700 hPa layer Sea for the cold season and in the 500 hPa layer for t1he warm season. We show the formation of a zone of anomalous moisture content in the Carpathian region, associated with moisture flow in the troposphere. We determine 20-year trends in moisture content in the 500 hPa layer (warm season). By analyzing the periodicity of the positive and negative phases of the Arctic Oscillation index we find the conditions that lead to the formation of zones of anomalous moisture content in the Carpathian region. We demonstrate the relationships between AO and moisture content at the level of 2 and 5-year harmonics in the 500 hPa layer (warm season), and 3.5 and 5-year harmonics in the 700 hPa layer (cold season). © 2022 SPIE.
