From what I can tell, the major difference btwn these results isn't the eddy heat flux at 10hPa which is almost equally impressive in all models, but eddy heat flux at 100-50mb. The CMC model is getting the biggest push from tropospheric wave activity, thus the biggest reversal. pic.twitter.com/fHoDVao4EY
