Structure of extreme precipitation field in Western Siberia

The present paper introduces the results of analyzing the space-time structure of extreme characteristics of precipitation in Western Siberia. For each index, with the view of changes evaluation, differences between average values for periods 1951-1980 and 1981-2010 were calculated. The assessment of synchronicity in time and space with the use of factor and cluster analysis showed that changes in precipitation of Western Siberia are determined by global climate-forcing processes only by one-third. When taking into account the results of division into classes, the share of the explained variance increases to 40-60%. The performed classification confirmed an increase in synchronicity when decreasing the territory scale. © (2015) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
