Sentences with phrase «scale variability reflected»
The decadal - scale variability reflected in the temperature reconstruction from tree rings may well be superimposed over this warmer baseline, but the warmth still would not likely match the observed average maximum temperatures over the past decade (17.54 °C mean maximum average for 1999 — 2008, Fort Valley, AZ, Western Regional Climate Center)(Table S1).

Lozier (p. 1507) discusses how recent studies have challenged our view of large - scale ocean circulation as a simple conveyor belt, by revealing a more complex and nuanced system that reflects the effects of ocean eddies and surface atmospheric winds on the structure and variability of the ocean's overturning.
As I indicated in an earlier blog, the natural variability at decadal time scales hinders the validation of any projection against observations, as these observations reflect just one possible trend.
BartH notes that «At relatively short time scales (say, a couple of decades), natural variability will dominate over systematic climate change, and there is more added value to expect from ensuring that the projections reflect natural variability adequately than to assess the degree to which the background climate changes.»
Downcore variations in bulk sedimentary δ15N appear to reflect century - scale variability in basin ventilation, attributed to changes in oceanographic conditions related to century - scale fluctuations in El Niño Southern Oscillation (ENSO).
