Hi GP, thanks for the update, very interesting but I am a bit confused why an increase in angular momentum (and an increase in westerlies?) only leads to a slight shift in the phase of the trough-ridge pattern so that the ridge is now to our east rather than the west. I would have thought that increasing the global momentum would reduce the amplitude of the trough-high-trough pattern causing the jet streams to increase making the weather patterns more unsettled.
Any thoughts?
Thanks
