I had been interested in finding out if climate change is making SSWs more common, the answer seems to be no but there is a case to be made that it is increasing their duration.
Anyone read anything else that studies this?
“Regarding long-term change, we found a statistically significant increase in the duration of SSW main-phase warmings of about 5(±2) d over the climate change period from the 1980s to the 2010s, raising the average duration by nearly 50 % from about 10 d to 15 d and inducing an SSW strength increase of about 40(±25) million km2 days from about 100 to 140 million km2 days.”
