While the polar vortex in the mid-stratosphere tends to recover quickly after these disturbances, any effects on the tropospheric jet stream and its weather patterns couldpotentially stick around for up to 6 weeksafter the vortex is disrupted.This “loads the dice” for potential arctic outbreaksov...
and also, there’s a delay," Judah Cohen, Ph.D. and an atmospheric and environmental scientist who studies the polar vortex, told FOX Weather. "So, you’ve been talking about a sudden stratospheric warming. It takes about two weeks for the effects of the sudden stratospheric...
Extreme polar vortex events known as sudden stratospheric warmings can influence surface winter weather conditions, but their timing is difficult to predict. Here, we examine factors that influence their occurrence, with a focus on their timing and verti
Month-to-month variation in the predictability of the stratospheric polar vortex in the Northern Hemisphere winter is examined on the basis of the systematic error and the ensemble spread of the North Pole temperature using a sevenyear archive of the operational ensemble one-month forecast dataset ...

Severe cold air outbreaks have significant impacts on human health, energy use, agriculture, and transportation. Anomalous behavior of the Arctic stratospheric polar vortex provides an important source of subseasonal-to-seasonal predictability of Northern Hemisphere cold air outbreaks. Here, through reanalys...
But here's the unsettling thought: this cold blast isn't the polar vortex-related severe one everyone is talking about (and that Mashable first warned you about on Dec. 6). After this cold snap, there are likely to be two more surges of Arctic air, each one of them as intense if ...
The present invention describes a method based on Asian polar vortex grid factors Icing long-term prediction method comprises the following steps: 1. collecting historical data and polar vortex icing information; 2 calculated Pearson correlation coefficients obtained icing predictor; 3. press the icing ...
Research during the last two decades has established that variability of the winter polar stratospheric vortex can significantly influence the troposphere, affecting the likelihood of extreme weather events and the skill of long-range weather forecasts. This influence is particularly strong following the ...
