Same Shit, that is precisely what science says. This will be the second time I have posted this, from Wikipedia's article on the polar vortex. Note, meanders (Rossby waves) occur when the vortex is weak.
"A study in 2001 found that stratospheric circulation can have anomalous effects on weather regimes.
[29] In the same year researchers found a statistical correlation between weak polar vortex and outbreaks of severe cold in the Northern Hemisphere.
[30][31] In more recent years scientists identified interactions with
Arctic sea ice decline, reduced snow cover,
evapotranspiration patterns,
NAO anomalies or weather anomalies which are linked to the polar vortex and
jet stream configuration.
[29][31][32][33][34][35][36][37] However, because the specific observations are considered short-term observations (starting c. 13 years ago) there is considerable uncertainty in the conclusions.
Climatology observations require several decades to definitively distinguish natural variability from climate trends.
