GCM projection of precipitation extremes in the mediterranean: changes ansd low frequency characteristic
Precipitation extremes simulated a medium by resolution GCM ( INMCM3.0) as are analyzed for the Mediterranean region. A structured analysis of low frequency variability in the control and forced ( corresponding to the IPCC scenarios) model runs is performed. The preliminary results of the analysis o...
