Changes in Precipitation Regime over the Territory of Russia: Data of Regional Climate Modeling and Observations

Аннотация

The study considers the problem of detailing climate projections with respect to changes in the precipitation regime over the territory of Russia by the middle of the 21st century. Numerous ensemble calculations with the high-resolution regional climate model are used to obtain the projections of climatic changes concerning the duration of dry and wet spells as well as in the related extremes of the amount and daily intensity of precipitation. The estimates of the trend in the analyzed precipitation characteristics derived from standard meteorological observations are presented for 1966–2015. Important seasonal and regional features of changes in the analyzed parameters of extremity are revealed. It is reasonable to consider these features when adapting to climate change at the regional level.
