Locked Jet Stream, Courtesy Of Global Warming, Bringing You Exciting New Weather Extremes!

[hatrack]

?t=4

Extreme gyrations of the jet stream are becoming more common, and that was only made more evident by the extreme setup that we have seen over the last week in North America, and indeed across the Atlantic.
More and more TV weather professionals are starting to explain the climate context of the day to day weather, especially extreme events. Above, two who have become friends, Jeff Berardelli, formerly of CBS News and now Chief Meteorologist at WFLA Tampa, and Chris Gloninger, Met Chief at KCCI Des Moines.

Immediately below, see the temperature anomalies (departure from normal) in the University of Maine’s highly useful Climate Reanalyzer. Big temperature differential set up by a jet peak up over Alaska, diving down over the central US, driving cold air south in the East, and warmer air north to Alaska, Greenland and across the Arctic.

Under that, from the same source, the jet stream set up, which lines up pretty well with the warm and cold extremes that we’ve been seeing. More and more scientists believe these kind of loopy jets are exacerbated by the loss of sea ice in the arctic, and a warming climate.

Having conversations with key experts on this, and will expand in next Yale Climate Connections video. For now, see my jet stream explainer below.

1. Really enjoyed the discussion posted and especially images. Never looked at the video

Thanks for posting!

[Dorn]

2. Thank you, you've given me another source for weather information

3. Interesting and important. Thx.

One question - will watch the video after coffee, but wonder if the thinking is that it's primarily the warming of the oceans that's causing the wobbles in the jet stream. And, is the slowing of the thermohaline circulation worsening because of that warming?

9. It looks like the main driver is polar warming - the flattening of temps between poles and equator

Jennifer Francis at Rutgers has some good videos on this - short and long:

11. Wow - thx. Will check these out.

We have to be informed, tho' it's mildly terrifying.
Thank you for your efforts.

4. The prospect of a stalling snowstorm or rainstorm are terrifying.

That could be catastrophic.

Two to three years ago a snowstorm dumped so much snow the weight collapsed a fabricated garage in the neighborhood and compromised my garage structure. I had to get a new garage.

Scary.

5. Nicely done!

6. give it a day..or four..the pnw is getting snow now

....and seattle getting first rain since....when....april?

7. KNR and bookmarking. For later.

8. Thus, the extremes climate scientists have been predicting for decades now....

as an unstable climate searches for a new, normal state. Fascinating stuff. Even more fascinating if we weren't actually living in this science experiment of our own making. Unfortunately, that new normal will probably include movement and / or expansions of the arid belts or horse latitudes into populated, agriculturally important regions. Think the Sahara moving north into Spain, Portugal and Mediterranean Europe. Or the Nebraska Sandhills reverting back to sand dunes. Western half of Texas, Oklahoma into Kansas and Colorado becoming even dryer to the point where agriculture of any kind may be out of the question. Ironic, since that's a where much of our domestically produced hydrocarbons currently come from.

10. I hate that the video began with Tucker bullshit

but quickly moved on to reality.
