Polar Vortex Sliding off Top of Planet

Arctic Weather Plunges into North America,
NASA Earth Observatory, January 30, 2019.


Broken Polar Vortex
“...disturbances in the jet stream and the intrusion of warmer mid-latitude air masses can disturb this polar vortex and make it unstable, sending Arctic air south into middle latitudes.”

Cold Records Threatened
“...predicting that air temperatures in parts of the continental United States will drop to their lowest levels since at least 1994, with the potential to break all-time record lows for January 30 and 31. With clear skies, steady winds, and snow cover on the ground, at least 90 million Americans could experience temperatures at or below zero degrees Fahrenheit...”

"The map above shows air temperatures at 2 meters (around 6.5 feet above the ground) at 09:00 Universal Time (4 a.m. Eastern Standard Time) on January 29, 2019, as represented by the Goddard Earth Observing System Model, Version 5. GEOS-5 is a global atmospheric model that uses mathematical equations run through a supercomputer to represent physical processes."

2014 Polar Vortex Video on UTube

So Very Cold
Note the center of the spinning Polar Vortex in the videos are not the North Pole, but the whole of Arctic Atmospheric Rotation is centered above the North end of Hudson's Bay. This current Vortex, like this one from 2014, is not merely a, "lobe," of cold air breaking off the Vortex, and moving South.

The Whole Enchalada
What we are seeing now, and back in 2014, is what happens when the whole Polar Vortex, who's spin is normally centered on the North Pole, slides off the top of the planet and begins rotating around a center above Hudson's Bay.

It brings huge amounts of cold to the South, and warmth to the North...

See the, "Lobe" type of a, "Polar Vortex."

Support Tahoe to Whitney

The Tahoe to Whitney Trail Guide and Magazine are walked, written, funded, and supported by my efforts, with the help of kindred spirits and my sister.

We offer valuable Trail Guide, Skills, Weather, News and Analysis.

My goal is to get you out to see your natural and social potential. Help me keep this unique resource accessible and expanding towards its potential. We've a lot of miles to cover ahead...

If you feel these efforts are valuable, I'm cordially inviting you to support them, here:



I am currently working towards publishing the completed guide between Tahoe & Yosemite as an e-book, while converting this "blog" to a fine magazine format. You will like the results! Help Tahoe to Whitney reach its potential!
