Sentences with phrase «decadal timescale»
The phrase "decadal timescale" refers to a period of ten years. It is often used in scientific studies or discussions to analyze changes, patterns, or events that occur over a span of ten years. Full definition

This analysis shows that on decadal timescales surface flux anomalies over the subpolar North Atlantic have the largest impact on the AMOC; however, on multi-decadal timescales (longer than 20 - 30 years), it is flux anomalies in the Arctic that become more important.
Carvalho 2007 shows in a tale of two islands (UK and NZ) that anti persistence is persistent, in both climate records over a couple of centuries and that the reversibility of regimes on decadal timescales when mapped onto random walks meets the Hurst criteria.
The long - term potential predictability of soil water variations in combination with the slow regrowth of vegetation after major disruptions leads to enhanced predictability on decadal timescales for vegetation, terrestrial carbon stock, and fire frequency, in particular in the Southern United States (US) / Mexico region.
Burgman, R. J., Clement, A. C., Mitas, C. M., Chen, J. and Esslinger, K. (2008), Evidence for atmospheric variability over the Pacific on decadal timescales GEOPHYSICAL RESEARCH LETTERS, VOL.

These recordings show that the volcano is active on a decadal timescale.
Such sudden flows are probably common events, with feedbacks allowing for drainage «on decadal timescales.»
New research published this week in the Journal of Climate reveals that one key measurement — large - scale upper - ocean temperature changes caused by natural cycles of the ocean — is a good indicator of regional coastal sea level changes on these decadal timescales.
(c) The PDO is actually inversely related to the sea surface temperature anomalies of that portion of the North Pacific on decadal timescales.
Climate change varies seasonally, on decadal timescales, and is geographically patchy [5].
For the most part, I've not seen much evidence to suggest that internal variations alone can bring the climate to a new state on decadal timescales, even if the internal fluctuations do not completely average out over decades (e.g.,, the PDO being in a positive phase more than a negative phase during the timescale of consideration).
From Karina (2014 Ocean Sciences p 547): «Our findings show that the area around the Tropical Asian Archipelago (TAA) is important to closing the global sea level budget on interannual to decadal timescales, pointing out that the steric estimate from Argo is biased low, as the current mapping methods are insufficient to recover the steric signal in the TAA region.»
One thing I am pretty sure about is that the tendency for el nino to occur near solar minimum and la nina to occur near solar maximum, and the capability of the ocean to store solar radiation on decadal timescales has led to an underestimation of the solar forcing.
It appears that Ghil, and others specifically warn against the use of MEM and temperature data: «Instrumental temperature data over the last few centuries do not seem, for instance, to determine sufficiently well the behavior of global or local temperatures to permit a reliable climate forecast on the decadal timescale by this SSA - MEM method.»
In short, CSIROâ $ ™ s expectation of change in annual rainfall in SE Australia, on a decadal timescale, ranges from nil to imperceptible.

The Atlantic Multidecadal Oscillation (AMO) is a naturally occurring pattern of sea surface temperature change that is seen in the North Atlantic Ocean on decadal timescales and affects weather and climate.
The Decadal Climate Prediction Project addresses a range of scientific issues involving the ability of the climate system to be predicted on annual to decadal timescales, the skill that is currently and potentially available, the mechanisms involved in long timescale variability, and the production of forecasts of benefit to both science and society
Component A comprises the production and analysis of an extensive archive of retrospective forecasts to be used to assess and understand historical decadal prediction skill, as a basis for improvements in all aspects of end - toend decadal prediction, and as a basis for forecasting on annual to decadal timescales.
