Polar diagrams of wind direction and intensity in different seasons. Data from the ECMWF Era Interim dataset (Berrisford et al. 2011) between 1991–2010 at 14.25E,40.5N (≈40 km from Vesuvius, 6 h averages, 29,220 records). Please note that, differently from the convention usually adopted in meteorology, these plots do not represent the direction of provenance of the wind, but the direction towards which the wind blows
