The advantage of recognising a reversed sign for the solar effect high up in the atmosphere is that it enables a scenario whereby the bottom up effects of ocean cycles and the top down effects of solar variability can be seen to be engaged in a complex ever changing dance with the primary climate response being changes in the tropospheric air circulation systems to give us the observed natural climate variability via cyclical latitudinal shifts in all the air circulation systems and notably the jet streams.
