I. Vilibic et al., FORCED AND FREE RESPONSE OF THE ADRIATIC SEA-LEVEL, Nuovo cimento della Societa italiana di fisica. C, Geophysics and space physics, 21(4), 1998, pp. 439-451
The aim of this paper is to improve the knowledge of the variations of
the sea level in the Adriatic Sea in the domains of forced and free o
scillations. For this purpose, one-year long-time series of data colle
cted at nine tide gauge stations placed on the eastern shoreline have
been collected and processed by spectral analysis. The harmonic consti
tuents have been calculated too. Semidiurnal and diurnal tides have go
t larger variations of amplitude on the islands than on the coast. The
response of the sea level in the domain of synoptic and planetary for
mations is quite synchronous in the whole Adriatic for periods longer
than 3.5 days, with a gap around 9.5 days. These formations excite the
sea level first in the North Adriatic, and then, secondly in the Midd
le and South Adriatic. The seiches occurred at already known periods o
f 22-23, 10.8 and 7.5-8 hours, and at a new one of about 4 hours. 4 ho
ur seiche occurs in the region inside the Middle Adriatic islands, and
it is predominantly influenced by the Sirocco wind forcing.
