Seasonal Mean Precipitation Rates

Figure TS.30

Figure TS.30. Spatial patterns of observed (top row) and multi-model mean (middle row) seasonal mean precipitation rate (mm day–1) for the period 1979 to 1993 and the multi-model mean for changes by the period 2090 to 2099 relative to 1980 to 1999 (% change) based on the SRES A1B scenario (bottom row). December to February means are in the left column, June to August means in the right column. In the bottom panel, changes are plotted only where more than 66% of the models agree on the sign of the change. The stippling indicates areas where more than 90% of the models agree on the sign of the change. {Based on same datasets as shown in Figures 8.5 and 10.9}
