Online climate change projections report 5.4 Examples of RCM data
Figures 5.3 to 5.5 show some results from the RCM ensemble; these are purely to illustrate the sort of data which can be accessed by the user, rather than to draw any conclusions about climate change. However, note that the LINK access does not provide any graphics capability, so these types of figures cannot be created online.
Figure 5.3 compares the simulated time series of summer (JJA) seasonal-mean daily maximum temperature from 1951–2099, from a 25 km grid square over Berkshire of each of the eleven RCM variants under the Medium emissions scenario. Figure 5.4 shows a similar set of time series of summer-mean precipitation for a grid square near Inverness; the large amount of noise due to natural variability is immediately apparent, showing that, despite a gradual reduction in summer precipitation through the 21st century, natural year-to-year changes remain larger than the projected climate change, even at the end of this period. Figure 5.5 shows maps of summer-average rainfall simulated by one RCM variant for two 30-year periods, 1961–1990 and 2070–2099.
