The MJO forecast divergence between the GFS & Euro is nuts. While I think the GFS is overzealous, I actually think it'll be closer to reality because the SSWE will accelerate the BDC, cooling/raising the tropical tropopause, effectively amplifying tropical convection & the MJO. pic.twitter.com/9f0ipTcOQk
