Weather and Climate Anomalies in Russian Regions Related to Global Climate Change

Abstract

Possible mechanisms for the formation of significant weather and climate anomalies in Russia in recent years and their relation to global climate change and natural quasicyclic processes are discussed. Extreme Russian heat wave in 2010, the Amur River flood in 2013, and extreme cold winters are analyzed. All these events were associated with the formation of long-lived blocking anticyclones whose frequency increase can be expected under conditions of global warming. To link such events with the global warming, the effects related to regional and global climatically significant natuial quasicyclic processes should be taken into account. They include the Atlantic Multidecadal Oscillation, Pacific Decadal Oscillation, and El Niño—Southern Oscillation.
