Figure 12.3: Latitude-month plot of radiative forcing and model
equilibrium response for surface temperature. (a) Radiative
forcing (Wm-2) due to increased sulphate aerosol loading at the
time of CO2 doubling. (b) Change in temperature due to the
increase in aerosol loading. (c) Change in temperature due to
CO2 doubling. Note that the patterns of radiative forcing and
temperature response are quite different in (a) and (b), but
that the patterns of large-scale temperature responses to
different forcings are similar in (b) and (c). The experi-ments
used to compute these fields are described by Reader and Boer
(1998).
