Explanation: 

Detailed explanation-1: -Siberia is known worldwide for its long, harsh winters, with a January average of −25 °C (−13 °F). Although it is geographically situated in Asia, Russian sovereignty and colonization since the 16th century have rendered the region culturally and ethnically European.

Detailed explanation-2: -Siberian air is generally colder than Arctic air, because unlike Arctic air which forms over the sea ice around the North Pole, Siberian air forms over the cold tundra of Siberia, which does not radiate heat the same way the ice of the Arctic does.

Detailed explanation-3: -Siberia is one of the coldest regions in Russia with an average daily high temperature of only 5 degrees. The climate is predominantly frosty cold and in the winter months the mercury does not even reach the positive range.

Detailed explanation-4: -The most well known feature of the Russian climate is its very cold winter, brought about by the country’s high latitudes (40-75°N), vast land mass and lack of any topographic obstructions to protect it from arctic winds sweeping across its long, north-facing and often frozen coastline.

Detailed explanation-5: -Modern conifer-dominated taiga of Siberia occurs between ∼68° and 50° N. The region is divided into three geographic areas: Northeast Siberia (Bering Strait to the Verkhoyansk Range), Eastern Siberia (Verkhoyansk Range to the Yenisei valley), and the Western Siberian Plain (Yenisei valley to the Urals).
