Figure 2.6: Doubled CO2 minus current climate annual mean differences in surface air temperature (top) and deep convection occurrence frequency (bottom) simulated by the GISS GCM.
The GISS GCM shows evidence of the dynamical and ocean mixed layer influences described
above in its regional patterns of cloud cover and sea level pressure change for a doubling of CO2
(Fig. 2.7). First, cloud cover decreases in the Atlantic and Pacific midlatitude storm tracks,
