Figure 9.12: The multi-model
ensemble annual mean change of the sea level pressure (colour shading), its range
(thin red isolines) (Unit: hPa) and the multi-model mean change divided by the
multi-model standard deviation (solid green isolines, absolute values) for (a)
the CMIP2 scenarios at the time of CO2-doubling; (b) the IPCC-DDC scenario
IS92a (G: greenhouse gases only) for the years 2021 to 2050 relative to the period
1961 to 1990; (c) the IPCC-DDC scenario IS92a (GS: greenhouse gases and sulphate
aerosols) for the years 2021 to 2050 relative to the period 1961 to 1990; (d)
the SRES scenario A2 and (e) the SRES
scenario B2. Both SRES-scenarios show the period 2071 to 2100 relative to the
period 1961 to 1990. See text for scenario definitions and description of analysis
technique.
