Sentences with phrase «scale variability»
The phrase "scale variability" refers to the extent to which something can change or vary in size, range, or measurement. It is used to describe how much flexibility or differences there can be in the measurements or value of something. Full definition

Since the TAR, developments in AOGCM formulation have improved the representation of large - scale variability over a wide range of time scales.
Rayner et al. (2003) used the method of Kaplan et al. (1997) but with certain changes to the method to explicitly resolve the long - term trend and improve small scale variability where observations were plentiful.
However, Figure 3.35, based on the newly developed Hadley Centre MSLP data set version 2 (HadSLP2; Allan and Ansell, 2006), suggests that although there exists a weakening trend starting in the 1920s, it is not reflected in the longer record extending back to the 1850s, which shows marked decadal - scale variability before the 1940s.
This simply arises from chance, and the fact that there are very few realizations of the century - scale variability present in the two short forcing series.
During the last glacial period, climate underwent rapid millennial - scale variability known as Dansgaard - Oeschger (DO) events, consisting of warm interstadials and cold stadials.
Most of the time, this data set reproduces well the large scale variability, except for a few seasons with limited sampling, in particular in winter along west Greenland or north - east of Newfoundland in presence of sea ice.
Finally, a small surface radiation and ceilometer system was deployed at the PNG Lombrum Naval Base about 6 km away from the Manus ARM site in order to provide some documentation of scale variability with respect to the representativeness of the ARM measurements.
Analyses of tide gauge and altimetry data by Vinogradov and Ponte (2011), which indicated the presence of considerably small spatial scale variability in annual mean sea level over many coastal regions, are an important factor for understanding the uncertainties in regional sea - level simulations and projections at sub-decadal time scales in coarse - resolution climate models that are also discussed in Chapter 13.
Even basic definitions as «weather» and «climate» or regional vs. global scale variability get muddled up.
When subgrid scale variability is inferred from the AGCM meteorology, dust emission shows significant improvement especially over the Sahara and Asia.
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).
These linear discriminants, which consist of an RASST anomaly field and a time series that describes the projection of that anomaly in the annual mean RASST field, maximize the ratio of inter-decadal to inter-annual variability, in keeping with our desire to understand the decadal - to - century scale variability in the global mean surface temperatures (see SI Text and Figs.
Because natural fire regimes varied widely historically, and are complicated in many places by similar variability in logging practices and intensities, the effect of fire reductions on bark beetle outbreaks varies considerably and involves several issues of spatial and temporal scale variability.
We use ensemble modeling all the time, and we use many runs that take the initial state of the atmosphere and perturbate it to various small degrees to either side such that when taken togther, the envelope is assumed to account for all such inconsistencies, abnormalities, non-adjustments, and small - scale variability such that the result can be presumed to be a solid representation of what's going on.
The data is on atmospheric absorption during occultations, indicating short time scale variability.

Do these studies confirm that natural warming trends have occurred, not exactly, but they do provide evidence which supports stronger centennial scale variability than is readily accepted.
Much of the inter-annual to decadal scale variability in surface air temperature (SAT) anomaly patterns and related ecosystem effects in the Arctic and elsewhere can be attributed to the superposition of leading modes of variability in the atmospheric circulation.
