Abstract
Results from investigation of the bora during the period of 20-25 March 1982 are characterized by a large variability od bora strength, direction and duration.
The two distinct wind speed maxima indicate two different origins of bora genesis. The first bora (21 March) was caused by a cold air stream, followed by the Genova cyclogenesis process. The second bora situation (23-25 March) is connected with the central Eyrope anticyclone and the cold NE flow - upstream of the Dinaric Alps.
Assuming that the bora has a certain similarity with the supercritical flows described by hydraulic theory, the parameters of the real flow could be successfully predicted on the entire northern Adriatic in the case with the strongest bora.
