Severe bora on the Northern Adriatic. Part I: Statistical analysis

The results of statistical analysis of severe bora (wind N-E direction and mean hourly wind velocity ≥ 17.0 m/s) occurrence at three locations on the northern Adriatic (Senj, Omišalj and Pula) are presented. Concerning the representativness of Senj it is shown that Senj's bora is not representative for a broader area in the northern Adriatic. ln the 30-year period of observation (1957-1986) 434 cases with severe bora were registered in Senj. On the other locations severe bora was not so frequent. Long severe bora usually occurs only during the winter season. The wind velocity is more uniform in situations with the longer lasting bora. Its basic characteristic of long bora duration is shown to be valid mainly for bora in the cold season particularly in Senj. Although the great majority of cases the strongest bora occurs in Senj, there are situations with maximum bora gusts greater at other localities.
