Further to my post earlier regarding the strat profile and i've done a little digging. Comparing the gfs to the ecm on the Berlin site they could not be more different. The ecm is now finally showing the 30mb zonal winds going negative from day 7 with excellent profile at day 10. Even 50mb goes negative at day 9. 10mb finally goes positive at day 10.
I suspect this is just a typical wobble by the gfs,if so we should see some much more amplified charts again from the model in the near future.
