The enormous size of Russia and the remoteness of many areas from the sea result in the dominance of the humid continental climate, which is prevalent in all parts of the country except for the tundra and the extreme southeast. Mountains in the south obstruct the flow of warm air masses from the Indian Ocean, while the plain of the west and north makes the country open to Arctic and Atlantic influences.
Most of Northern European Russia and Siberia has a subarctic climate, with extremely severe winters in the inner regions of Northeast Siberia (mostly the Sakha Republic, where the Northern Pole of Cold is located with the record low temperature of −71.2 °C/−96.2 °F), and more moderate elsewhere. The strip of land along the shore of the Arctic Ocean, as well as the Russian Arctic islands, have a polar climate.
The coastal part of Krasnodar Krai on the Black Sea, most notably in Sochi, possesses a humid subtropical climate with mild and wet winters. Winter is dry compared to summer in many regions of East Siberia and the Far East, while other parts of the country experience more even precipitation across seasons. Winter precipitation in most parts of the country usually falls as snow. The region along the Lower Volga and Caspian Sea coast, as well as some areas of southernmost Siberia, possesses a semi-arid climate
