The preliminary results of this study have been on our website since the time the flooding happened, but now we have looked not only at the rainfall, but also the influence of anthropogenic greenhouse gas
emissions on the atmospheric circulation and how this propagates from rainfall, to river flow down to the direct impact of flooded houses in the river catchment zones.
My point, which I hope you would likewise concede, is that even with a weakened or shut - off THC, western Europe would still remain warm relative to other land masses at the same latitudes (possibly even warmer than British Columbia, as it is now), based
primarily on atmospheric circulation patterns.
As the authors point out, even if the whole story comes down to precipitation changes which favor ablation, the persistence of these conditions throughout the 20th century still might be an indirect effect of global warming, via the remote effect of sea surface
temperature on atmospheric circulation.
Thanks — but your comment about SE Australia conflicts with your previous
comment on atmospheric circulation, as such a small area is unlikely to have a meaningful relationship between heat and rain however statistically significant your negative correlation may be (what is the t?).
Associated with our
work on atmospheric circulation patterns we are studying energy transport in the earth system and the transport of water in the atmosphere on different time and space scales.
The generalised time
series on the atmospheric circulation forms for 1891 - 1999 were kindly placed at our disposal by the Federal Arctic and Antarctic Research Institute (AARI) in St. Petersburg (Russia).
But in a given model you can often find ways of altering the model's climate sensitivity through the sub-grid convection and cloud schemes that affect cloud feedback, but you have to tread carefully because the cloud simulation exerts a powerful
control on the atmospheric circulation, top - of - atmosphere (TOA) and surface radiative flux patterns, the tropical precipitation distribution, etc..
Local and regional changes in the character of precipitation also depend a great
deal on atmospheric circulation patterns determined by El Niño, the North Atlantic Oscillation (NAO; a measure of westerly wind strength over the North Atlantic in winter) and other patterns of variability.
The top priorities should be reducing uncertainties in climate sensitivity, getting a better understanding of the effect of climate
change on atmospheric circulation (critical for understanding of regional climate change, changes in extremes) and reducing uncertainties in radiative forcing — particularly those associated with aerosols.
The latter is not equivalent to climate change not playing a role, because such results are obtained when the effect from a warmer atmosphere is in the opposite direction to the effect
on the atmospheric circulation.
The transfer of sensible heat and evaporation fluxes are particularly critical because they feed back
on the atmospheric circulation, clouds, sea ice, temperature, and humidity.
Since these drivers are not globally diffuse, might they have some impact
on atmospheric circulation, and hence regional climate shifts?
Volcanic eruptions have complex, major effects
on atmospheric circulation and may well temporarily disrupt the TLC reflection — SST relationship.
The reconstruction could also help understand SAMOC variability from interannual to decadal timescales and its impacts
on atmospheric circulation, climate, and extreme weather from an observational perspective.
Their influence
on the atmospheric circulation is focused on the polar regions by the Earth's magnetic field [the opposite phase of the changes in the Arctic and the Antarctic can be explained by the phenomenon of «solar system dissymmetry» as a result of which fluctuations of solar constant occur].
