[:ja]NASAの地球観測衛星Suomi NPPが撮影した10月のシベリアの降雪です。
シベリアは、ロシア連邦領内のおよそウラル山脈分水嶺以東の北アジア地域です。高緯度地域で冬季の気温は非常に低く、早いところでは8月下旬に降雪を見ます。オイミャコンでは-73度という人間が居住可能な場所における最低気温を記録しています。一方、夏季は30度以上まで気温が上昇することがあるという、いわゆる大陸性気候です。冬の日本列島の天気を支配するシベリア寒気団は、夜間の放射冷却による極寒気がシベリアに蓄積され、そこから吹き出すと考えられています。植生は、タイガと呼ばれる針葉樹を中心とした広大な森林地帯が大半を占めます。より緯度の高い地域は地衣類を中心としたツンドラと呼ばれる植生であり、樹木は生育しなくなります。

[Earthview Wonders] No.883: October Snow in Siberia🇷🇺
NASA’s Suomi NPP satellite captured October snow in Siberia.
The territory of Siberia extends eastwards from the Ural Mountains to the watershed between the Pacific and Arctic drainage basins. Vegetation in Siberia is mostly taiga, with a tundra belt on the northern fringe, and a temperate forest zone in the south. The climate of Siberia varies dramatically, but it typically has short summers and long, brutally cold winters. On the north coast, north of the Arctic Circle, there is a very short (about one-month-long) summer. By far the most commonly occurring climate in Siberia is continental subarctic (Koppen Dfc or Dwc), with the annual average temperature about −5C and an average for January of −25C and an average for July of +17C.
The local scenery on the ground is as follows.
