Figure 10.6: Analysis of inter-model consistency in regional precipitation change based on the results presented in Figure 10.5. Regions are classified as showing either agreement on increase with an average change of greater than 20% ("Large increase"), agreement on increase with an average change between 5 and 20% ("Small increase"), agreement on a change between -5 and +5% or agreement with an average change between -5 and 5% ("No change"), agreement on decrease with an average change between -5 and -20% ("Small decrease"), agreement on decrease with an average change of less than -20% ("Large decrease"), or disagreement ("Inconsistent sign"). GG is the greenhouse gas only case (see Figure 10.5a), and, GS, the greenhouse gas with increased sulphate case (see Figure 10.5b). In constructing the figure, ensemble results were averaged to a single case, and "agreement" was defined as having at least of four the five GG models agreeing or three of the four GS models agreeing.
