Skill in predicting the S〨 pattern is not high beyond week 2 in any model, in contrast to the zonal pattern. We find that the relationship between the S〨 pattern and enhanced eddy heat flux and a weakened polar vortex is initially well‐represented but significantly decays with lead time ...
Define polar front. polar front synonyms, polar front pronunciation, polar front translation, English dictionary definition of polar front. n. The region or boundary separating air masses of polar origin from those of tropical or subtropical origin. Amer
evolution of the vortex event is captured remarkably well. This highlights an influence from this region previously unrecognised by the seasonal forecast community. We suggest that better representation of the flow in this region is likely to improve predictability of extreme polar vortex events and ...
Forecasters believe a disruption to the current flow will happen in the new year, but early indications are that the air mass won’t send the country into tundra territory. A stable Arctic Polar Vortex. (FOX Weather) "There isn’t a one-to-one correlation between what’s happening with t...
My radio career began doing weekend weather forecasts which is odd because I used to know next to nothing about weather. That's why I defer to the experts from the National Weather Service when it comes to forecasts. They just said that the polar vortex
With a piece of the Polar Vortex camped out in the North Central U.S.(near historic cold for this time of year), storm systems have been like a parade traversing the periphery of the vortex. This has brought heavy snow and ice to the Deep South, with major disruptions to travel and ...
The polar vortex, a swirl of low-pressure air six miles up in the atmosphere, blasted much of the American Midwest and Northeast in late January 2019 with temperatures cold enough to bring on frostbite within minutes.

The “polar vortex” is the deep cyclonic flow around a cold air mass generally covering the Arctic, Canada, and Northern Asia during winter. It is irregularly shaped, following the far-northern land masses, unlike it’s stratospheric cousin, which is often quite symmetric and...
