1) During the time period when CO2 measurements have been made in Mauna Loa the most visible changes in the increasing rate of the atmospheric CO2 content are caused
by the seasonal variability in the exchange rate of CO2 between biosphere and atmosphere; e.g. Bob Tisdale http://i37.tinypic.com/al6ips.jpg.
This shortfall can be further compounded
by seasonal variability.

The report, led
by PhD student Richard Hall and Professor Edward Hanna from the University of Sheffield's Department of Geography, discovered that up to 35 per cent of this
variability may be predictable — a significant advance which may help in the development of
seasonal forecasting models.
The community [studying]
seasonal and longer climate
variability was (and still is) dominated
by the ocean community and especially a decade ago [the El Niño Southern Oscillation] ENSO was the only boundary forcing that anyone was paying attention to.
There can / will be local and regional, latitudinal, diurnal and
seasonal, and internal
variability - related deviations to the pattern (in temperature and in optical properties (LW and SW) from components (water vapor, clouds, snow, etc.) that vary with weather and climate), but the global average effect is at least somewhat constrained
by the global average vertical distribution of solar heating, which requires the equilibrium net convective + LW fluxes, in the global average, to be sizable and upward at all levels from the surface to TOA, thus tending to limit the extent and magnitude of inversions.)
Lead author Dr Debbie Polson, of the University of Edinburgh's School of GeoSciences, said: «This study shows for the first time that the drying of the monsoon over the past 50 years can not be explained
by natural climate
variability and that human activity has played a significant role in altering the
seasonal monsoon rainfall on which billions of people depend.»
«A climate pattern may come in the form of a regular cycle, like the diurnal cycle or the
seasonal cycle; a quasi periodic event, like El Niño; or a highly irregular event, such as a volcanic winter... A mode of
variability is a climate pattern with identifiable characteristics, specific regional effects, and often oscillatory behavior... the mode of
variability with the greatest effect on climates worldwide is the
seasonal cycle, followed
by El Niño - Southern Oscillation, followed
by thermohaline circulation.»
Come on Richard, The

Simulations
by regional climate models show good agreement with observations in the
seasonal and spatial
variability of the joint distribution, especially when an ensemble of simulations was used.
The region is strongly affected
by seasonal and interdecadal climate
variability, such as El Niño events and the Pacific Decadal Oscillation.
In the near surface snow air, we observed during late spring and summer
variability of GEM concentrations on a daily timescale induced
by chemical processes, as well as a
seasonal shift in these chemical mechanisms.
Sampling errors estimated from different reanalyses and from
seasonal forecasts yield qualitatively comparable spatial patterns, in which the actual values of uncertainties are controlled
by the magnitudes of synoptic
variability.
Moreover, the linear relationship that the Zhai study fits between the
seasonal variability derived relationship of low cloud reflectivity with SST and ECS is dominated
by «bad» models that are inconsistent with the observational constraint.

seasonal climate
variability through my company CFAN, my perspective on uncertainty and confidence in context of prediction, and how to convey this, has utterly and irreversibly changed.
