(12) Vela Luka, 6 July 1978
It is briefly stated in a newspaper
article (Slobodna Dalmacija, 7 July 1978) that “the sea was rising and falling with
amplitude of one meter”. The author also comments that a month ago such variability would pass
unnoticed but that after the large previous event the local people were alarmed
and therefore decided to remove about seventy boats from the inner part of Vela
Luka Bay.
The synoptic situation during the event was characterized by weak pressure gradients over the Mediterranean and most of Europe, and corresponding weak surface winds. At the 850-hPa level, warm air was advancing from the northern Africa across the central Mediterranean towards the Adriatic Sea, with weak upper-level temperature gradients over the middle and the southern Adriatic. An upper level trough can be seen at the 500 hPa level – with associated strong mid-tropospheric winds (> 30 m/s) of southwesterly to westerly direction blowing at its front side, over the western Mediterranean and the Adriatic Sea.
