West Siberian Plain. The transition from winter to summer and from summer back to winter is very quick so that effectively there are only 2 seasons over most of Russia Annual precipitation is mostly not particularly high and is spread throughout the year with a summer convective peak.

Examples of annual average precipitation are mm at Moscow but only mm further east at Chelybinsk, Novosibirsk and Irkutsk. Most winter precipitation in Russia falls as snow but this, though frequent, is rarely very heavy and strong winds often sweep the ground bare of snow The greatest amount of precipitation falls out in mountains of Caucasus up to 2, mm per year , in the south of the Far East up to 1, mm , and also in a forest zone of East European plain up to mm. The minimum precipitation falls at semiarid areas of Prikaspijskaya lowland about mm per year The average annual temperature in European Russia currently rises at a rate of 0.

In — the number of summer seasons with extremely hot days has doubled with respect to earlier period — No statistically significant systematic changes have been found in duration of the extreme events: the long-lasting hot events of and appear to stand alone rather than being manifestations of a general trend According to observations provided by the meteorological network of Roshydromet, the warming in Russia was 1.

Furthermore, the mean warming in the country was 1. The annual maxima and minima of daily surface air temperature increased, and the difference between them decreased minima grew faster than maxima. The number of frosty days decreased. Data show that during the mean annual surface air temperature increased by 0.

Warming is more evident in winter and spring and more intensive east of the Urals 7. Warming expressed in terms of annual means is mainly due to substantive increases of temperatures in the colder periods. In warm periods, the increase in temperature trend is typical only for the Eastern Siberia and the north-western regions of Russia except for the White Sea region. Minor cooling or no clear tendency is observed for the remaining territory In Russia, as a northern country, the warming is growing faster, than for the Earth as a whole.

Temperatures in the Arctic are rising at almost double the rate of the global average. In many inland Arctic regions, surface air temperatures have warmed 0.

In some regions of Russia, in particular in Siberia, the acceleration rate of annual-mean temperature is more than 4 times higher than that of the global temperature. Moreover it was the warmest year overland of the Northern Hemisphere according to the data of CRU from the middle of the 19th century 2.

Over a large part of the territory of Russia the increase of the vegetation period was noted. It is related to both the earlier beginning of spring and later autumn.

At the same time the opposite tendencies are revealed in a number of regions 2. Observations show that winter has shortened by weeks in the European part of the former Soviet Union during the period The severe heat wave in western Russia was influenced both by natural climate variability and anthropogenic climate change Climate variability led to extremely low soil moisture content.

Evapotranspiration was very low due to the very dry soil that cannot provide enough water to evaporate. As a result, little of the available surface net radiation was used for evaporation and turned into latent heat flux and most of it was turned into surface warming sensible heat flux.
