  abstract = {{ERA}-40 reanalyses, and simulations from three regional climate models ({RCM}s) ({ALADIN}, {LMDZ}, and {WRF}) and from one statistical downscaling model ({CDF}-t) are used to evaluate the uncertainty in downscaling of wind, temperature, and rainfall cumulative distribution functions ({CDF}s) for eight stations in the {F}rench {M}editerranean basin over 1991-2000. {T}he uncertainty is quantified using the {C}ramer-von {M}ises score ({C}v{M}) to measure the "distance" between the simulated and observed {CDF}s. {T}he ability of the three {RCM}s and {CDF}-t to simulate the "climate" variability is quantified with the explained variance, variance ratio and extreme occurrence. {T}he study shows that despite their differences, the three {RCM}s display very similar performance. {I}n terms of global distributions (i.e. {C}v{M}), all models perform better than {ERA}-40 for both seasons and variables. {H}owever, looking at variance criteria, {RCM}s are not always much better than {ERA}-40 reanalyses, whereas {CDF}-t produces accurate results when applied to {ERA}-40. {I}n a second step, a combined statistical/dynamical downscaling approach has been used, consisting in applying {CDF}-t to the {RCM} outputs. {I}t shows that {CDF}-t applied to the {RCM} outputs does not necessarily produce better results than those from {CDF}-t directly applied to {ERA}-40. {I}t also shows that {CDF}-t applied to {RCM}s generally improves the downscaled {CDF}s and that the "additional" added value of {CDF}-t applied to the {RCM}s is independent of the performance of the {RCM}s in terms of {C}v{M}, explained variance, variance ratio and extreme occurrence.},
