“…For winter, no significant signals have been found due to the strong influence of the mid-latitude baroclinic disturbances (Dumenil-Gates & Ließ 2001). Sanchez et al (2007) performed a simulation where they substituted trees with grass, and found a significant decrease in summer precipitation of up to 3 mm d -1 due to lower evapotranspiration and an increased surface temperature of up to 3 K. In Heck et al (2001), afforestation caused a maximum cooling of 2 K during May, while during August a warming of 1 K was observed. This sign reversal is a direct consequence of the faster springtime drying out of the soil moisture in the afforestation simulation.…”

We investigated the impact of land-cover changes on regional climate over the EuroMediterranean area. For this purpose, we compared a control simulation, which employs the presentday vegetation cover, with 2 different potential vegetation distributions performed with the regional climate model RegCM3 for the time period 1981-2000. The simulation results show how land-cover changes are able to modify both the thermodynamics and dynamics of the lower troposphere in central Europe, particularly during summer. Within some of the regions where land-cover change occurred, we found significant changes in heat fluxes, while weak changes were found in surface temperature and precipitation fields. Changes in vegetation composition modify the probability density function of the 2 m temperature, and hence land-cover changes may have a strong impact on extreme events.

“…The RCMs used in this paper were the Rossby Centre RCM version 3.5 (RCA), (Kjellström et al 2005, Samuelsson et al 2006, the Prognostic at the Mesoscale version 2.4 (PROMES), (Sanchez et al 2007, Dominguez et al 2010, the ICTP Regional Climate Model version 3 (RegCM3), (Pal et al 2007, da Rocha et al 2009) and the Modele de Circulation Generale du LMD version 4 (LMDZ) (Li 1999, Hourdin et al 2006 Both GCMs and RCMs are characterized by systematic errors in the representation of the atmospheric circulation and related variables. In this study, systematic biases in temperature and precipitation were removed by applying the "quantile-based mapping" bias correction method to the monthly data (Wood et al, 2002;Saurral, 2010).…”

The Iberá wetlands, located in La Plata Basin, is a fragile ecosystem habitat of several species of flora and fauna and it also constitutes one of the largest inland freshwater of the world. In this study the hydroclimatologic response to projected climatic changes in the Iberá wetlands is assessed. Bias corrected temperature and precipitation data from four Regional Climate Models (RCMs) developed for the CLARIS-LPB project were used to drive the calibrated Variable Infiltration Capacity (VIC) hydrological model for different time slices. Derived future scenarios consist on changes in temperature, precipitation and water level of the Iberá Lake for the periods 2021-2040 and 2071-2090 with respect to present. All RCMs are consistent in predicting a warming for the near future (0-2ºC) and also to the end of the century (1.5-4.5ºC) in the study region, but differ in the sign and percentage of precipitation changes. VIC modeling results suggest that the Iberá Lake level could increase in the 21 st century and that this increment would be higher in the summer months. Nevertheless, the projected 10 cm of water level increase could be not so relevant as it is of the same order of magnitude than the observed interdecadal variability of the system.

“…Climate model studies for the temperate regions showed that replacing forests with agriculture or grasslands reduces the surface air temperatures (Bonan, 1997;Bounoua et al, 2002;Oleson et al, 2004) and the number of summer hot days (Anav et al, 2010). Other studies show opposite results, where temperate forests cool the air compared to grasslands and croplands and contribute to higher precipitation rates in the growing season (Copeland et al, 1996;Hogg et al, 2000;Sánchez et al, 2007). In the Mediterranean region climatic effects of forest cover change can also vary during the summer months (Heck et al, 2001).…”
