Severe bora on the mid-Adriatic

The Adriatic severe bora can partly be explained by the two-dimensional hydraulic theory, as one of the possible mechanisms of a strong surface downslope wind. A comparison of the application of the hydraulic theory shows a similar severe bora mechanism on the northern and mid-Adriatic, with the exception of the Senj area where special bora effects have been observed. As the theory could not completely explain Adriatic bora, this required a study ofa three-dimensional bora structure. The results have been achieved through analyses of the interaction of the upstream bora structure (sounding measurement at Zagreb and Belgrade) and the downstream bora structure at Split. The only available aerological data at Split date back to the period 1959-1963 and can be used for a comparison of estimated hydraulic parameters on the lee side.
