The knowledge of strong wind climatology is important for the precise forecast of their occurrence and also for the elaboration of efficient protection methods against their harmful effects. In meteorology, strong winds are defined as atmospheric phenomena characterized by air currents with a speed of ≥ 15m/s (calculated for a time period of 2'). In the synoptic activity, the average wind speed of ≥ 10m/s (calculated for a time period of 10') is included in the category of “warning messages”, characteristic to the dangerous meteorological phenomena. The strong winds represent one of the risk hydrometeors with particular impact on the agricultural activities (especially on the tree and vine culture). The well-known marine breezes are formed close to the sea (up to 15-20 km inside the province) and they influence positively the relative air humidity but also contribute to a decrease in the rain regime. Thus, Dobroudja has been known as the land of winds since Antiquity. The wind speed is between 18-90 km/h, while the frequency is up to 85%, the dominant directions being north, north-west and north-east (43.8%), then south and south-east (30.4%).
