Analysis of an intense bora event in the Adriatic area.
Bora is a cold, strong, low level wind which blows mainly from NE along the Adriatic coast. However, bora-like winds occur in other regions i.e. Antarctic slope winds, Boulder windstorms. Cold air, forced through channels between higher terrain and accelerated by katabatic effects, can reach downslo...

Bora is a cold, strong, low level wind which blows mainly from NE along the Adriatic coast. However, bora-like winds occur in other regions i.e. Antarctic slope winds, Boulder windstorms. Cold air, forced through channels between higher terrain and accelerated by katabatic effects, can reach downslope very high speed, with strong spatial gradient and temporal variations. This wind affects coastal area and alters significantly the Adriatic sea status. Nowadays is still difficult to predict accurately its intensity, longevity and internal structure, which are related to mesoscale features as well as to local effects. Moreover, high resolution is needed. The meteorological Eta model is used to study the features of an intense real bora event recently occurred in the Adriatic area.
