The improved simulation of ENSO amplitude is mainly due to the reasonable representation of the thermocline and thermodynamic feedbacks: On the one hand, the deeper mean thermocline results in a weakened thermocline response to the zonal wind stress anomaly, and the looser vertical stratification of mean temperature leads to a weakened response of anomalous subsurface temperature to anomalous thermocline depth, both of which cause the reduced thermocline feedback in g2; on the other hand, the alleviated cold bias of mean sea surface temperature leads to more reasonable thermodynamic feedback in g2.

The sea ice in the Siberian Arctic is peaking, its effect on the meridional temperature gradient strong, promoting increased zonal flow of large - scale winds, which advect warm air and moisture over the Eurasian continent from the Atlantic and disrupt vertical stratification near the surface and promote high cloudiness, both of which lead to increasing temperatures — greatest at low altitudes and high latitudes.

Hawkins and Jones (2013) focused on one small aspect of Callendar's work: his compilation of World Weather Records station temperature data into zonal and global temperature anomalies, in effect, delimiting Callendar, whose contribution was much more diverse, as a sort of John the Baptist of temperature accountancy, merely preparing the way for Phil Jones.

Unfortunately, there is actually quite good model agreement on the overall pattern over the East Pacific through the end of the month: the huge ridge over the Eastern Pacific is expected to persist and perhaps grow even more, continuing the extraordinarily dry pattern over California but allowing for occasionally large swings in temperature as a very cold airmass over Canada is occasionally able to spill westward in weak or even slightly retrogressive (east to west) zonal flow.

For example, the zonal - mean profiles of atmospheric temperature changes in models subject to «20CEN» forcing (includes CO2 forcing) over 1979 - 1999 are discussed in Chap 5 of the U.S. Climate Change Science Program [Karl et al. 2006].

Now, as the global trend swings from warming to cooling these winds switched from zonal to meridional flow causing dramatic increases in variability of temperature and precipitation.

Note that I am not saying that warming has not taken place just that it is not global — BEST admits that 30 % of the stations have cooled and that is true of severla of therse long term stations — but that we should concentrate on finding a useful set of temperature trends in regional and zonal areas that reflect the impacts of climate change, as for example the Sahel, and understand the true reasons without assuming carbon dioxide to be the culprit.
