si andrea... :-) ma il mio intento era di aprire una discussione centrata sulla previsione di roeder in riferimento a quanto effettivamente avvenuto

infatti "attendendo il nuovo aggiornamento"

Esattamente opposte a quelle precedenti.....

Ecco il commento del professore:

"After the "witterung" and the events in the last days of December it has become clear that the January temperature deviations in Northern Germany will have a range between 4 and 7 K above the normal temperature.
The problem is, what will happen then. The stratospheric circulation now will intensify rapidly after the warming in the last days of December. A further wave energy exchange with the stratosphere will therefore happen in the 2nd half of January. As it is not sure that then the stratosperic circulation may break down to a farer extend then before, there will remain a lot of uncertainty. The stratospheric polar vortex may remain stable and very strong because of the increased cooling there due to the higher content of greenhouse gases.
On the other hand there can be observed a rapid decrease of the ENSO warm event. ( s. floods over Sumatra after a drought in November). The additional warming effect to the troposphere will diminish and the Pacific low pressure activity will spread westward. Under the present conditions of the changing climate the number of comparable cases is reduced. So the prognoses are supported only by a few examples. "
