Figure 8.5: Components of
space-time errors of surface air temperature (climatological annual cycle) simulated
by CMIP2 model control runs. Shown are the total errors, the global and annual
mean error (�bias�), the total r.m.s (�pattern�) error, and
the following components of the climatological r.m.s. error: zonal and annual
mean (�clim.zm.am�); annual mean deviations from the zonal mean (�clim.zm.am.dv�),
seasonal cycle of the zonal mean (�clim.zm.sc�); and seasonal cycle
of deviations from the zonal mean (�clim.zm.sc.dv�). For each component,
errors are normalised by the component�s observed standard deviation. The
two left-most columns represent alternate observationally based data sets, ECMWF
and NCAR/NCEP reanalyses, compared with the baseline observations (Jones et al.,
1999). Remaining columns give model results: the ten models to the left of the
second thick vertical line are flux adjusted and the six models to the right are
not. From Covey et al. (2000b).
