This study examines changes in an AT-500 hPa surface pressure field across two natural periods of the earth's climate system: a period of stabilization and the second wave of global warming, divided into an active phase and a decelerated warming phase. The study area is the Atlantic-Eurasian sector of the hemisphere, where weather and climate instability is the highest. An analysis of climatic fields is performed for January and July. It is established that in both January and July the highest degree of zonality is typical for the active phase of the second wave of global warming. It is found that in January the climatic baric wave shifted along the west–east direction between natural climatic periods. A westward shift is observed during the stabilization period and the decelerated warming phase. Eastward wave movement is observed in the active phase of the second wave of global warming. In July, in the context of the west–east shift of the baric wave over most of European Russia, during the decelerated warming phase there emerged an anticyclonic core, which indicates an increase in the frequency of anticyclones over this territory. It is suggested that this restructuring of the pressure field contributes to an increase in the role of summer transformation processes in the ongoing climate warming. [ABSTRACT FROM AUTHOR] |
