In the new study, researchers tested their hypothesis that a chain of events in the troposphere caused the sudden stratospheric warming and subsequent splitting of the polar vortex.

Saturn’s hazy moon Titan has a long-lived Earth-like winter polar vortex supercharged by the moon’s peculiar chemistry. A new study finds Titan’s northern hemisphere polar vortex sticks around past the moon’s summer solstice, into what would be late June on Earth, lasting three-quarters of a Titan year, or about 22 Earth years.

The Arctic Sea ice continues to run at record lows, and this has potentially large implications on the winter ahead. Instead of white ice reflecting what little sunlight is available north of 60 degrees, we have ocean water rapidly losing its heat into the atmosphere of the High Arctic. The ice that’s usually there now acts as an insulator to hold in the heat, but not this year! How all …

I’ve been busy with the GOES-R launch, but am also following the incredible situation in the High Arctic, where Arctic Sea ice continues to run at record low levels. More like falling of a cliff actually, and the only word I can come up with is astonishing! There is a real temperature dipole showing up between the warm Arctic and the very cold areas of Russia/Asia where the snowfall was …

In spite of valiant attempts by my fellow broadcast meteorologists to stop it, the so-called polar vortex is back and being blamed for just about everything again. Let me show you why this is dead wrong, and if you see a story in mass media blaming a cold air outbreak on the polar vortex, I can say categorically that it’s wrong. DEAD WRONG. There IS such a thing as a polar …

That message is going around twitter this Friday afternoon, courtesy of many meteorologists. My friend Stu Ostro at The Weather Channel posted a nice graphic about it that is worth sharing!
