Climate Model Predicts Very Cold Winter in Northern Hemisphere

Bloomberg reports:
About 14.1 million square kilometers of snow blanketed Siberia at the end of October, the second most in records going back to 1967, according to Rutgers University’s Global Snow Lab. The record was in 1976, which broke a streak of mild winters in the eastern U.S. In addition, the speed at which snow has covered the region is the fastest since at least 1998.

Taken together they signal greater chances for frigid air to spill out of the Arctic into more temperate regions of North America, Europe and Asia, said Judah Cohen, director of seasonal forecasting at Atmospheric and Environmental Research in Lexington, Massachusetts, who developed the theory linking Siberian snow with winter weather.

“A rapid advance of Eurasian snow cover during the month of October favors that the upcoming winter will be cold across the Northern Hemisphere,” Cohen said in an interview yesterday. “This past October the signal was quite robust.”...

Last year, 12.85 million square kilometers covered Eurasia at the end of October. By January, waves of frigid air were pummeling the U.S.
