Abstract

The wind output from atmospheric models is a fundamental forcing data of oceanic models. Here we consider the wind output from the ALADIN and IFS models and compare it with the results of scatterometer and altimeter estimates of wind speed for the Adriatic Sea. We use data of 19 different meteorological and platform stations for comparisons. A five year period from 2009 to 2012 is considered for the comparison. As a consequence, we conclude that overall both models give very similar statistical results with a scatter index of 0.33 for IFS and 0.35 for ALADIN for the altimeters. The difference is that ALADIN appears to be better in the Northern Adriatic while IFS seems better in the Southern Adriatic. A possible explanation could be that the higher resolution of ALADIN is crucial to resolve the bora wind in the Northern part of the Adriatic.
