The Russian Far East covers 6.63 million sq. Mountain ranges break up these zones into irregular flows as temperate conditions reach far north along the Pacific Coast, while subarctic conditions persist on high mountain ridges in the south. In these regions summer is humid, as monsoon storms come in from the south. Autumn is also wet, particularly in Primorskiy Krai. Winter is cold and dry, as strong air masses flow east from Siberia.
Spring is long and cool.
A Siberian or continental climate defines the interior Magadan Oblast, western Amur Oblast, and all of Yakutia. Summer is short but warm. Winter is long, dry, and very cold. The mountains along the Pacific coastline keep the warmer maritime climate from reaching the interior. The great volcanoes of Kamchatka are higher, with Klyuchevskiy Volcano rising 4,750 meters.
