Our feeling is that once the validation becomes more comprehensive, most of the extremely high sensitivity examples will fail (particularly on the seasonal cycle, which tests for variations rather than just a mean).

The main changes in radiative forcing from the precessional cycle are in the latitudinal and seasonal distribution, not in the global mean, which is why the nature of the response can be expected to be different from doubling CO2.

Also, just because the average pole - to - equator temperature gradient is decreasing doesn't mean that the seasonal variation won't still be in place, and then there's the whole issue of the hydrologic cycle intensification — a moister atmosphere carries more latent heat and thus may generate more intense mid-latitude storms as well.

Perhaps surprisingly, the spread in the seasonal cycle in the reanalyses is small once the annual mean has been removed.

On a (2011) Climate Etc. post Pondering the Arctic Ocean, I interpreted the record in the context of a (qualitative) change point analysis, defined by changes in trend, mean value, amplitude of the annual cycle, and interannual variability.It looks like 2013 was another change point year, characterized by low amplitude seasonal cycle.

The relations between the length of a solar cycle and the mean temperature in the following cycle are used to model Svalbard annual mean temperature and seasonal temperature variations.

[4] The aspects of each of these measures that are used as predictors are their climatology (the 2001 - 2015 mean), the magnitude (standard deviation) of their seasonal cycle, and monthly variability (standard deviation of their deseasonalized monthly values).

These are all cell mean values on a grid with 37 latitudes and 72 longitudes, giving nine predictor fields each with 2664 values for three aspects (climatology, seasonal cycle and monthly variability) for each of three variables (OLR, OSR and N).

One sentence summary: A strengthened subtropical jet stream — which is the primary means by which El Niño brings increased precipitation to California — is unlikely to occur prior to winter due to the intrinsic seasonal cycle of temperature variations across the Pacific Basin.

A number of techniques have been employed to sub-set or recalibrate these projections based on different aspects of the observed ice cover, including the mean and / or seasonal cycle of ice extent (e.g., Stroeve et al., 2007, 2012a; Wang and Overland, 2009, 2012), historical ice cover trends (Boe et al., 2009), and ice volume and thin ice area (Massonnet et al., 2012).

The direct radiative forcing (DRF) is strongest in the Northern Hemisphere summer when the insolation is the highest although different seasonal cycles of the sulphate burden from the chemical transport models result in maximum global mean radiative forcings ranging from May to August (e.g., Haywood and Ramaswamy, 1998), the ratio of the June - July - August / December - January - February radiative forcing being estimated to lie in the range less than 2 (e.g., van Dorland et al., 1997) to > 5 (e.g., Penner et al., 1998b; Grant et al., 1999) with a mean of approximately 3.3.
