Sentences with phrase «dynamical changes»
The phrase "dynamical changes" means alterations or shifts that happen over time, in an energetic or active manner. It refers to ongoing modifications or transformations in a system or situation. Full definition
Did they really think that the public, journalists, and sceptics would read (or even understand) the small print in the sea level column stating «Model - based range excluding future rapid dynamical changes in ice flow»?

Estimates of the decadal variability in ice sheet mass loss (11) suggest the impact on acceleration estimates is ∼ 0.014 mm / y2 for a 25 - y time series, in the absence of rapid dynamical changes in the ice sheets.
Such dynamical changes favor certain types of weather situations in some regions and others elsewhere.
Stratospheric temperatures, particularly near the pole are also significantly influenced by dynamical changes, and in particular, the strength of the polar vortex that is set up every winter at the edge of the polar night.
``... We present a new analysis of millions of ocean temperature profiles designed to filter out local dynamical changes to give a more consistent view of the underlying warming.
Additionally, there is some observational evidence that atmospheric dynamical changes may explain the recent cooling over parts of Antarctica..
Hatun et al. examined the possibilities that [i] a change in rain falling over the ocean (freshens the water) and evaporation (increases the salinity by removing water and leaving salt behind), [ii] increased salinity in the sub-tropical gyre (in the main part of the North Atlantic), [iii] increased salinity in the sub-polar gyre, or [iv] dynamical changes in the relative contributions from the two gyres could explain the high salinities in the in - flow regions.
Reading your post and following some of the literature on dynamical changes it is tempting to conclude that the difference may be due to acceleratded ice sheet flow in Greenland and Antarctica that is not accounted for in the models.
Like the melting of a wide region of Polar ice causes all kinds of meteorological dynamical changes causing droughts several thousand miles away.
At high latitudes a number of features play a role — different changes in sea ice and snow cover and their reflectivity; varying atmospheric and ocean dynamical changes; as well as cloud cover effects.
In his Environmental Research Letters paper Hansen claims that the IPCC 2007 figures are low because the IPCC says it is unable to evaluate possible dynamical responses of the ice sheets and therefore its figures do not include any possible rapid dynamical changes in ice flow.
Stratospheric temperatures, particularly near the pole are also significantly influenced by dynamical changes, and in particular, the strength of the More»
Indeed, the IPCC goes out of its way to make clear that its projections exclude «future rapid dynamical changes in ice flow» — changes we are already seeing in both Greenland and Antarctica (subs.
Of course, most IPCC scientists don't believe that rapid dynamical changes in ice flow can happen!
They do not include «rapid and dynamical changes in ice flow», because the IPCC was too uncertain about how likely or influential these changes might be.
This includes the loss of reflectivity («albedo») caused by sunlight striking dark exposed rock rather than white ice, the lubricating effect of melt water penetrating to the bottom of glaciers, and many other «dynamical changes».
A. A., 2009: Dynamical changes in the ENSO system in the last 11,000 years, Climate Dynamics, Volume 33, Issue 7 - 8, pp 1069 - 1074: 10.1007 / s00382 -008-0469-4
«The reason the Arctic and Antarctic did not get really mentioned in the arctic is because the dynamical changes that relate to dry and wet areas (in the region) is just not well - known,» he said.
The contributions from ice sheets include the contributions from ice - sheet rapid dynamical change, which are also shown separately.
They also suggest that there would be complex spatial patterns of response â $ «local warming in the lower stratosphere, increases in reflected solar radiation, decreases in outgoing longwave radiation, dynamical changes in the northern hemisphere winter circulation, decreases in tropical precipitation etc..
Now it seems you just don't like the answer because it interferes with your intention to use the «dynamical changes» to jump on the «it's all natural variations!»
These dynamical changes are strongly coupled to thermodynamic and radiative processes that govern the global warming.
Concerning the impact on extreme temperature events (winter cold spells, summer heat waves), these dynamical changes appear to be secondary compared to the long - term warming trend that results in fewer and less intense winter cold spells, and more frequent and intense summer heat waves in mid-latitudes.
Recent observations (summarized by Alley et al. (2005); see references therein) of acceleration of glaciers behind the collapsed Larsen B ice shelf, of ice streams in the Amunden Sea sector of West Antarctica, and of many Greenland outlet glaciers suggest that the time - scales for ice - dynamical changes may be much shorter.
