In the rekognition of the uncertainties, the IPCC Good - Practice - Guidance - Paper on using climate model results offers some wise advice (first bullet point under section 3.5 on p. 10): the local climate change scenarios should be based on (i) historical change, (ii) process change (e.g. changes in the driving circulation), (iii) global climate change projected by GCMs, and (iv) downscaled projected change.

The analysis also follows the advice in the IPCC Good - Practice - Guidance - Paper on using climate model results: the local climate change scenarios should be based on (i) historical change, (ii) process change (e.g. changes in the driving circulation), (iii) global climate change projected by GCMs, and (iv) downscaled projected change.

Dynamical versus statistical downscaling for the generation of regional climate change scenarios at a Western Mediterranean basin: the Júcar River District

Methodological advances since the TAR have focused on exploring the effects of different ways of downscaling from the climate model scale to the catchment scale (e.g., Wood et al., 2004), the use of regional climate models to create scenarios or drive hydrological models (e.g., Arnell et al., 2003; Shabalova et al., 2003; Andreasson et al., 2004; Meleshko et al., 2004; Payne et al., 2004; Kay et al., 2006b; Fowler et al., 2007; Graham et al., 2007a, b; Prudhomme and Davies, 2007), ways of applying scenarios to observed climate data (Drogue et al., 2004), and the effect of hydrological model uncertainty on estimated impacts of climate change (Arnell, 2005).

In the last 10 years, downscaling techniques, both dynamical (i.e. Regional Climate Model) and statistical methods, have been developed to obtain fine resolution climate change sceClimate Model) and statistical methods, have been developed to obtain fine resolution climate change sceclimate change scenarios.

Our 2015 study examines the impact of 21st - century projected climate changes (CMIP5, RCP4.5 scenario) on a number of tropical cyclone metrics, using the GFDL hurricane model to downscale storms in all basins from one of the lower resolution global atmospheric models mentioned above.

The first paper (Flower et al., 2013) used downscaled climate data from global climate models, subject to three different emissions scenarios, to examine the effect of projected climate change on the distribution of Douglas Fir and three types of spruce.

Working from a set of projections from eight different global climate models being driven by three different emissions scenarios, the authors used statistical downscaling to drive a hydrology model to determine what changes could be seen to the hydrology of these regions.
