Regional Peculiarities of Changes in the Normals of the Main Climatic Parameters in Russia

The regional features of changes in the normals of the main climatic parameters (air temperature, precipitation, water vapor tension, atmospheric pressure at sea level) on the territory of Russia for three 30-year periods, 1961–1990, 1981–2010, and 1991–2020, are studied. Seasonal changes in the regime of the main climatic parameters in certain regions of Russia over the past decades have been revealed. In the last thirty years, there has been a slowdown in warming in all seasons on the territory of Russia. Summer precipitation normals of 1991–2020 decreased in most of the country, however, a significant increase in precipitation was found in the southern regions of Yakutia, the Amur oblast, and Primorye. For the regime of atmospheric pressure at sea level, the greatest changes are manifested in winter. The differences in climatic normals obtained in this work can be considered as one of the indicators of climate change that manifest themselves differently in different regions of such a vast country as Russia. The information can be useful for developing preventive adaptation measures under changing climate.
