Convective potential of the atmosphere of Western Siberia amid global climate change

In the process of warming, the atmosphere of Western Siberia gets warmer and wetter due to local sources of moisture. This is accompanied with amplification of convection processes in the warm seasons and increasing frequency of extreme weather phenomena. Trends in atmospheric instability and their causes on a territory located in the Ob-Irtysh interfluve and limited by 50–64 °N, 60–95 °E, including the Vasyugan Swamp, are analyzed. The swamp boundaries distinctly marked on temperature maps in the last decade indicate changes in the thermal radiation of the swamp surface. These changes in heterogeneity of heating and heat exchange are reflected in changes in atmospheric instability as well. The greatest changes in the atmospheric temperature mode have been observed in the Great Vasyugan Swamp.
