Figure 9.11: The multi-model
ensemble annual mean change of the precipitation (colour shading), its range (thin
red isolines) (Unit: %) 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.
