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).
