Bone-chilling lows swept transcontinental Russia during the first half of this week. The nearby nations of Kazakhstan, Mongolia, Uzbekistan, Turkmenistan, and eastern China have also suffered.
Asia's temp anomalies Nov. 25, 2019
On Tuesday, November 26, Russia’s Verhojansk station reported a vodka-chugging –54C (-65.2F).
A November reading below -50C (-58F) is considered “extreme,” said Severe Weather Europe, adding that the pattern supporting such a phenomenon is “led by a disturbance of the polar circulation, allowing outbreaks of frigid cold air-masses to spread south into Russia.”
Scientists have long-understood that studying the jet stream is key to understanding weather and climate, but to properly study the jet stream attention must turn to the sun — something not so widely perceived.
Low solar activity disrupts that band of meandering air flowing some 6 miles above our heads, reverting its usual tight Zonal flow to a weak Meridional one. This wavy flow diverts cold Arctic air to the lower-latitudes –where us humans reside– and shifts warm Tropical air north:
Well, Greenland’s cold temperatures didn’t up and vanish, they didn’t escape Earth’s atmosphere and leak into space — they were simply diverted south by a wavy jet stream. It is THIS mechanism which fully explains why the far-northern-latitudes are experiencing pockets of unusual heat of late, while the lower-latitudes have been suffering outbreaks record-smashing cold:
