Abstract
Two cases of strong bora on the southern and the northern Adriatic coast, 2 - 3 December 1983. and 10 - 11 February 1984, related to the strong upstream wind conditions, are presented. The bora was caused by a strong cold air inflow from the northeast resulting from a large scale synoptic situation characterized by an anticyclone over western Europe and a cyclone over the Adriatic.
The application of Smith's (1985) hydraulic theory shows that these bora cases are characterized by strong wind in the deep upstream bora layer and low effective mountain height.
The hydraulic theory proved appropriate in considering the observed effects in spite of poor steady-state approximation. Much greater descrepancies from the theory are observed in the bora case of February 1984.
