The rank histogram approach, as applied here
over spatial fields of nine time - averaged climate variables and one trend, represents a leading - order diagnostic of the behaviour of an ensemble.

Her development of a grid in the late 1950s wherein she gently inscribed penciled lines
over subtle
fields of color marked a turning point in the history of abstract painting and established the geometric and
spatial language that she continued to refine
over the ensuing decades.
With her gentle inscriptions of penciled lines on subdued
fields of wash and color, Martin established a geometric and
spatial language that she would refine and reinterpret
over ensuing decades.
«This study investigates past sea level reconstruction (
over 1950 — 2003) based on tide gauge records and EOF
spatial patterns from different 2 - D
fields.
Although teleconnections are best defined
over a grid, simple indices based on a few key station locations remain attractive as the series can often be carried back in time long before complete gridded
fields were available (see Section 3.6.4, Figure 3.31); the disadvantage is increased noise from the reduced
spatial sampling.
[T] he basis of the results are correlations
over a very restricted set of locations (predominantly western Europe, Japan and the USA) which project strongly onto naturally occurring patterns of climate variability, or are with
fields with significant amounts of
spatial auto - correlation.
New gridded daily wind
fields from Metop / ASCAT scatterometer retrievals are produced in near real - time
over global ocean with a
spatial resolution of 0.25 °.
If we are trying to estimate the average temperature
over a wide area like the U.S. or the Globe, it is advisable to use gridding or some more complicated form of
spatial interpolation to assure that our results are representative of the underlying temperature
field.
For example, the regional model Im working on, will get the temperature correct for the entire
field (averaged
over 30 years) but the trend is the wrong direction and its a disaster in the
spatial dimension
These range from simple averaging of regional data and scaling of the resulting series so that its mean and standard deviation match those of the observed record
over some period of overlap (Jones et al., 1998; Crowley and Lowery, 2000), to complex climate
field reconstruction, where large - scale modes of
spatial climate variability are linked to patterns of variability in the proxy network via a multivariate transfer function that explicitly provides estimates of the spatio - temporal changes in past temperatures, and from which large - scale average temperature changes are derived by averaging the climate estimates across the required region (Mann et al., 1998; Rutherford et al., 2003, 2005).

Lukovich et al. (Centre for Earth Observation Science, U. of Manitoba); 4.4 to 4.5; Heuristic - Dynamics The absence of a strong and persistent sea level pressure high
over the Beaufort in July together with the absence of
spatial homogeneity in the springtime sea ice drift
fields suggest that continued sea ice decline will be an artifact of increased temperatures and thermodynamic forcing rather than the considerable dynamical contributions seen in summer of 2007.
