3.2. Statistical Downscaling of Climate Change Projections
It is more effective to use different types of AOGCMs and emission scenarios in determining future climate change. This helps to identify a wide spectrum of different climate change projections and allows a possible comparison between different emission scenarios. Although most AOGCM outputs are available for all three emission scenarios, this study selects only six AOGCM model results.
The cumulative probability distribution of the projected future daily rainfall records for Colombo shows that there will be some extreme events with great intensities. The distribution patterns for all six model outputs show more or less similar extreme events (Figure 6).
