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.
