Climate modelling at coastal scales: the case of the Adriatic Sea

Published on 09/10/2020 (last modified 09/10/2020)

The climate module of the AdriSC (Adriatic Sea and Coast) coupled atmosphere-ocean model has been developed by the researchers of the Institute of Oceanography and Fisheries (Partner of CHANGE WE CARE project) to obtain a resolution of 3 km and 1 km in the atmosphere and the ocean, respectively, in order to predict changes in physical properties and processes at coastal scale.

Regional atmospheric and ocean climate models usually operate at resolutions between 12 and 50 km, so they are unable to predict changes in physical properties and processes at coastal scale, e.g. at kilometric scale. To overcome this problem, researchers of the Institute of Oceanography and Fisheries (www.izor.hr) implemented the climate module of the coupled atmosphere-ocean model AdriSC (Adriatic Sea and Coast) by increasing its resolution at scale of  few kilometres.  

The implemented model may be considered an important tool for modelling the trend of prominent winds within future climate change scenarios, especially in those regions presenting complex orographies and bathymetry, such as the Adriatic Sea, where the surrounding mountains contribute to control the wind regime, characterized mainly by Bora and Scirocco.

Based on these results, produced also as part of CHANGE WE CARE project,  two research papers has been published in a leading climate peer-review journal, Climate Dynamics (https://www.springer.com/journal/382).
