![enter image description here][1] Figure 4.1: Climate change (RCP 4.5 and RCP 8.5) impact on the waves defined as the median and root-mean-square (RMS) of the bias (scenario minus evaluation results) of the maximum significant heights, the maximum peak periods and the mean wave directions of the 22 bora events The spatial variations of the extremes and the 1-min time series – extracted along the open Adriatic Sea, reveal that, under warming climate change (for both RCP 4.5 and RCP 8.5 scenarios), significant wave heights and peak wave periods are likely (1) to strongly decrease over the entire domain, with a south-eastward shift of direction during the extreme bora events, and (2) to decrease in the northern Adriatic with no change in direction during the extreme sirocco events. These results are in good agreement with previous studies which estimated the possible future changes in wind speed over the Adriatic region, for the 2041-2070 period, from an ensemble of 19 high‐resolution (0.11°) CORDEX simulations and found that overall the mean wind speed as well as the number of storms is reduced under the RCP 8.5 scenario for both bora and sirocco conditions. ![enter image description here][2] Figure 4.2: Climate change (RCP 4.5 and RCP 8.5) impact on the northern Adriatic extreme sea levels defined as the median and root-mean-square (RMS) of the bias (scenario minus evaluation results) of the maximum sea levels for the 14 sirocco events In addition, under climate change projections with imposed PGW methodology, the northern Adriatic sirocco storm surges are not only likely to decrease but also to be less frequent, which is in accordance with the analysis of the sirocco wind and storm surge projections. However, as (1) the subsidence of the Venice Lagoon is not considered in this study, and (2) the sea level change is imposed as a mean effect for the entire 2060-2100 period in the PGW methodology and the Atlantic global sea level rise is ignored, these results do not imply that flooding of the Venice city will be less likely in the future.
