Аннотация: Abstract. The features of the spatial and temporal distribution of the main meteorologicalvalues in the Northern Hemisphere in 2019 are considered. A brief description of climatechange on the background of long-period variability of extreme meteorological phenomena,which identified by WMO climate indices, is given. Quartile analysis and nonparametricMann-Kendall criterion are used to assess the significance of changes in the frequency andintensity of extreme meteorological phenomena in different regions of Russia. The increase inthe growth of the average temperature in the Northern Hemisphere in the spring and summer of2019 compared to 2018 and early 2019 is noted. The prolonged large-scale anomalies ofweather regimes were observed in the warm period of 2019: heatwaves in Western Europe, inthe south of European Russia, in Siberia, Alaska, and as well heavy rainfall in the Irkutskregion and in the south of the Far East. Possible mechanisms of weather and climate changes inthe Northern Hemisphere are discussed. The focus is on the Arctic, which is the mostvulnerable to climate warming. It is concluded that, with an abundance of physical hypotheses,there are many contradictions and uncertainties in the study of the mechanisms of weather andclimate variability. Solving the problems requires further research based on moderntechnologies, the development of satellite monitoring systems and hydrodynamic modeling.
