Statistical downscaling models from the RIWER2030 ANR project (Lafaysse et al. 2014; Hingray et al. 2013). Predictors used by the models are as follows: SLP: sea level pressure; Z: geopotential height for the pressure level; Ta: surface temperature; u and υ: zonal and meridian geostrophic wind; HU: relative humidity; and Fq: moisture flux, where subscripts refers to pressure level (hPa). The number of generation for each GCM–SDM chain is 100.
