AdriaClim: The evolution of the number of Bora wind days

ARPA FVG, Project Partner 11 in INTERREG IT-HR AdriaClim project, carried out a study on the evolution of the number of Bora wind days, which is expected on the Gulf of Trieste in the next decades, according to three different Representative Concentration Pathways (RCPs), i.e. climate scenarios for the concentration of greenhouse gases.

 

 

This study, based on an ensemble of 14 numerical models belonging to the EURO-CORDEX initiative, shows that a statistically significant increase in the number of days with "moderate" to "strong" (about 14 days every 10 years) and “strong” (about 4 days every 10 years) Bora wind is expected, only in case of RCP 8.5 (the scenario that does not foresee any action for the mitigation of climate change, that is business as usual). Furthermore, the significant trends characterize the summer season, but not the winter one.

These results, which requires further investigation, are particularly relevant in the study of climate change impacts on regional coastal waters mixing and they contribute to the achievement of the WP 3 objectives of the AdriaClim project.
