Russia experiences the most extreme continental climate range of any country on Earth, spanning eleven time zones and four climatic zones from subarctic tundra to humid subtropical. The Koppen climate classification identifies humid continental (Dfb, Dfa), subarctic (Dfc, Dwd), tundra (ET), and small areas of humid subtropical (Cfa) along the Black Sea coast. January temperatures in Yakutsk average minus 38.6 degrees Celsius, while Sochi on the Black Sea coast averages 6.1 degrees Celsius the same month. This 44.7 degree differential within one nation's borders in a single month represents the widest temperature variance for any country. Annual precipitation ranges from 2,000 millimeters in the Caucasus Mountains to under 200 millimeters in portions of eastern Siberia. The Ural Mountains create a moisture barrier that produces distinct climate patterns between European Russia and Siberia.
