Shantalinskiy 1 T.R. Auhadeev 1 Kazan (Volga Region) Federal University,18 Kremlin str., Kazan, 420008, Russian Federation The space-time variability of atmospheric pressure fields, the air temperature and wind velocity in the troposphere of the Northern Hemisphere within the period from 1948 to 2013 has been described. A delay of air temperature low-frequency component against the atmosphere zonal circulation variations in the 30-70° N latitude zones in winter time has been revealed. The share of the wind velocity component in the temperature variation is 60%. As an example, the air temperature response to the impact of a number of circulation systems in the Volga region has been considered. https://www.biotech-asia.org/vol11_nospl_edn2/climate-trends-in-barometric-circulation-regime-and-the-thermal-state-in-the-northern-hemisphere-and-its-individual-regions/ Macro-circulation system; zonal wind; circulation indexes; Correlation coefficient; air temperature; atmospheric pressure
