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).
