Found Stephen Wilde's paper .. See
Basically, more energy into the oceans causes more vigorous Hadley cells pushing all the jet streams poleward increasing the polar vortex reducing cloudiness in temperate latitudes and increasing the amount of heat that enters the oceans in temperate latitudes. Reduce the energy by reduction of UV and the opposite occurs - Hadley cells become smaller and less vigorous and jet streams become more meridonal and Rossby waves more extreme resulting in more cloud in latitudes reducing the amount of heat entering oceans.
Certainly, the jet streams have over the last few years moved equatorward and become more meridonal; the large Rossby waves have led to the Texas drought, the preceding Russian heat wave, the continual cold wet weather in Europe etc.
Hi Nautonnier! and on the same time what have happened with ocean currents? Some changes?
As you´ve always said -and Sig agreed- main drivers of Earth´s weather and climate are oceans; which sounds very reasonable to me. I understand -correct me if wrong- that ocean´s always have a lag respective changes as it accumulates or release Heat on delay.
Any recent trend changes in Gulf-Stream? Artic Ocean?
Could they be related -if any- with recent trends of Jet-Streams?
Thanks in advance
