extratropics

In the extratropics, variations in tracks and intensity of storms reflect variations in major features of the atmospheric circulation, such as the North Atlantic Oscillation.

The results are quite different for the north extratropics and especially the north polar oceans.

In the face of this evidence,Lorenz et al 2006 and predecessor article Kim et al QSR 2004 have proposed anewish theory that is gaining sway in Team-world – that there was Holocene Optimum warming in the extratropics, but there was tropical cooling in the Holocene Optimum.

I asked myself why the authors did not otherwise summarize all the trends in the tropics and extratropics and compare them with the seasonal computer simulations.

Lorenz et al 2006: "Tropical Cooling" « Climate Audit 2007

We now know that conditions at this time were probably warmer than today, but only in summer and only in the extratropics of the Northern Hemisphere.

Holocene Optimum « Climate Audit 2007

Mathematically, the amount of heat transferred from the tropics to the extratropics is under-determined.

If anything, the fact that the extratropical satellite measurement sees more of the stratosphere than it does in the tropics, due to a lowere tropopause height in the extratropics, the tropics should show greater warming just from this stratospheric effect.

Obviously the speleothem data from Oman and Dongge shows that the Holocene Optimum was very marked in these areas and not just the NH extratropics.

It would be the RSS or UAH TMT for the tropics and for the extratropics north and south. jae

Only the northern extratropics and north polar ocean show warming.
