Sentences with phrase «decadal scale internal»

Not exact matches

Another interesting question concerning a new Maunder Minimum would be the impacts on decadal - scale prediction, where both internal variability and changes in TSI are competitive with changing greenhouse gases.

Either there's a large decadal - scale internal variability driving it, such as a large pseudo-cyclical increase in deepwater formation, or the Arctic Ocean is near marginal stability under perturbation.

While rereading the ocean heat content changes by Levitus 2005 at http://www.nodc.noaa.gov/OC5/PDF/PAPERS/grlheat05.pdf a remarkable sentence was noticed: «However, the large decrease in ocean heat content starting around 1980 suggests that internal variability of the Earth system significantly affects Earth's heat balance on decadal time - scales.»

The IPCC treats natural internal variability as «noise»; we argue that it is the fundamental climate signal on decadal to century time scales, with external forcing projecting onto these modes.

natural internal variability can be pretty large on decadal to century time scales, and minimization of this variability by the hockey team has been very damaging to the science and the identification and intepretation of natural variability.

Additional proxy records that cover the entire CE are needed to investigate decadal - to centennial - scale responses of climate to changes in radiative forcing as well as internal variability at these time scales.

I don't know of any way to robustly increase or decrease a model's internal variability on decadal and longer time scales.

If there are centennial internal variations — and looking back over the holocene it looks to me there are — then «reversions to mean» over a centennial scale will look like a trend on which shorter decadal length variations will be superimposed.

«The figure clarifies that internal climate variability over a short decadal or 15 - year time scale is at least as important as the forced climate changes arising from greenhouse gas emissions.»

Natural factors such as the Sun (84 papers), multi-decadal oceanic - atmospheric oscillations such as the NAO, AMO / PDO, ENSO (31 papers), decadal - scale cloud cover variations, and internal variability in general have exerted a significant influence on weather and climate changes during both the past and present.

It is well - known that changes in temperature on decadal time scales are strongly influenced by natural and internal variations, and should not be confused with a long - term trend (Easterling and Wehner, 2009; Foster and Rahmstorf, 2011).

All six individual runs with bias - adjusted SST (only the average is shown) give simulated land air temperatures close to those observed so that internal model variability is small on decadal time - scales compared to the signal being sought.

The quality of agreement between model simulations with 20th century forcing and observations supports the likelihood that models are adequately simulating the magnitude of natural internal variability on decadal to century time scales.
