Description
Summary:The variability of Northern Hemisphere circulation types from 1899-2018 are analyzed and the classification of atmospheric circulation types in the early 21 st century are shown. These are associated with the frequency of dangerous weather phenomena, natural processes, and disasters within Russia during this time. Against this background, the synoptic conditions for the formation of extreme precipitation and floods, as well as natural fires in 2019 are considered. It is shown that an increase in the frequency of occurrence of stationary anticyclones and blocking flow regimes as well as an extension of the Mediterranean storm track was associated with an increase in the frequency of extreme precipitation and dangerous natural processes. Additionally, the occurrence of thunderstorms, often dry, led to the development of natural fires.
