The January–March 2014 North American cold wave was an extreme weather event that extended through the late winter months of the 2013–2014 winter season, and was also part of an unusually cold winter affecting parts of Canada and parts of the north-central and northeastern United States. [5] The event occurred in early 2014 and was caused ...
The 2014 Bering Sea bomb cyclone at peak intensity on November 8, over the Bering Sea.This system triggered the cold wave across North America. On November 8, the northward movement of a bomb cyclone associated with Typhoon Nuri's remnants shifted the jet stream far to the north, creating an omega block pattern, which allowed a fragment of the polar vortex to descend from Arctic region into ...
The February 2021 North American cold wave was an extreme weather event that brought record low temperatures to a significant portion of Canada, the United States and parts of northern Mexico during the first two-thirds of February 2021. The cold was caused by a southern migration of the polar vortex, likely caused by a sudden stratospheric ...
The polar vortex, which is a storm at the jet stream level of the atmosphere, has kept frigid air pent up above the Arctic Circle for much of the winter. When the polar vortex remains strong as it ...
The "polar vortex" that plunged Canada and the U.S. into historical cold last winter is said by researchers to have occurred because melting polar ice changes weather patterns, according to a ...
2014–15. The 2013–14 North American winter was one of the most significant for the United States, due in part to the breakdown of the polar vortex in November 2013, which allowed very cold air to travel down into the United States, leading to an extended period of very cold temperatures. The pattern continued mostly uninterrupted throughout ...
In Caribou, Maine, following a high of 20 on Thursday, temperatures will start the day on Saturday at 28 degrees below zero.The record low is 30 below zero set in 1971. Temperatures are forecast ...
A more typical weak tropospheric polar vortex on January 5, 2014. A circumpolar vortex, or simply polar vortex, is a large region of cold, rotating air; polar vortices encircle both of Earth's polar regions. Polar vortices also exist on other rotating, low- obliquity planetary bodies. [ 1] The term polar vortex can be used to describe two ...
