Sun, L., Deser, C. & Tomas, R. A. Mechanisms of stratospheric and
tropospheric circulation response to projected Arctic sea ice loss.
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.
