**Watch out for ghosts!** This is something that doesn't exist, but doomers are pushing it. Nothing in the stratosphere can influence weather on the surface. The density ratio is more than a 1000 to one. It gets all the press now, and will be forgotten tomorrow.

@hasmis sudden stratospheric warming events actually do have an impact on surface weather conditions, but are also caused by tropospheric conditions. More detail from NWS: weather.gov/bis/sudden_stratos

@ingalls That's possible, but unmeasurable, because the effect would be below noise of the surface influences. Nobody can separate that in my alternate physics dimension, but it is a common thing for influencers to say the butterfly can turn the hurricane. :) All things are possible....

@hasmis Oh I’m not saying it isn’t being blown out of proportion by the clickbait crowd, but SSWs have been a useful tool for us in the Pacific Northwest to predict lowland snow events 2-3 weeks out.

The earliest mention I remember of it associated with a forecast was 2019. SSWs are caused by, and then further disrupt, the wave pattern on the southern edge of the polar vortex (another term that is clickbaited into oblivion).

@ingalls Yeah, it's probably a good flag. I would think it is hard to separate an energy event on the surface, having an effect on the stratosphere. So far, in my physics world of one, I see massive energy events that follow the laws of physics. I put Occam's razor away for now, too sharp and deadly. :)
