As polar vortex season winds down, so does Season 1 of the Polar Vortex Blog. In our final post of the season, we discuss whether the season is ending on a cliffhanger or just tying up loose ends.
When we get to spring, the polar vortex's days are numbered. When will the "final stratospheric warming" occur this year?
Cold in the eastern U.S. can be a side effect of a sudden stratospheric warming event. But how reliable is it?
After a brief respite, the stratospheric polar vortex is expected to weaken again, and another major sudden stratospheric warming could be on the way.
A major disruption of the stratospheric polar vortex occurred. What happens next? The stratosphere will try to communicate its artistic vision down to the troposphere, but the troposphere may have its own masterpiece in mind.
The latest forecast says a major disruption of the polar vortex is on its way, but the stratosphere has been acting up for a while. Our bloggers explain what it might mean for U.S. weather.
Recent atmospheric patterns don't match those that typically precede a sudden stratospheric warming event. But forecasts do suggest the polar vortex might get stretched out of shape in coming weeks.
If this blog teaches you one thing, we want it to be this: "polar vortex" is not a synonym for "cold snap."
Winter returned with a vengeance to many regions in February and March. Our guest blogger, Dr. Amy Butler, explains why winds in the stratosphere may have been a key player.
Guest blogger Amy Butler explains how changes in the stratospheric polar vortex can influence the "usual" effects of El Niño on the climate in the Northern Hemisphere.
