“…Moen [1984] pointed out that the principal driving forcing of the cyclonic gyre is the eastward wind jet blowing from the Bonifacio Strait. As shown by the direct measurements effected in this area [TEMPO Group, 1991;Guymer and Zecchetto, 1993], the wind intensity is greater directly east of the strait than it is either to the north or to the south, where the strait is sheltered by Corsica and Sardinia, respectively. A divergence zone that causes upwelling is then produced to the north, and it is associated with a convergence zone to the south that causes downwelling.…”

The principal hydrographic structures and dynamic conditions of the northern Tyrrhenian Sea are studied through the comparison of in situ field data and a modeling simulation. The field observations are long‐term Eulerian and Lagrangian current measurements associated with two hydrographic campaigns conducted in late summer and in winter. The data indicate that a well‐marked cyclonic gyre affecting the water column from the surface to the bottom is present in the northern Tyrrhenian Sea in both periods. The gyre undergoes significant seasonal changes in both shape and size. Following the indications of past studies, a numerical quasi‐geostrophic model driven by the wind jet blowing from the Strait of Bonifacio was able to reproduce the principal gyre characteristics. However, the wind jet alone does not explain all the gyre features, especially its seasonal variation. A study of the model results and field data indicates that these variations are linked to the seasonal variability of the northward surface current flowing along the eastern boundary of the Tyrrhenian Sea.

“…The other strong wind of the Adriatic is the sirocco, which blows from the southeast along the axis of the sea [see Guymer and Zecchetto , 1993, Figure 14]. Sirocco events can cause storm surge flooding in Venice and they have been studied both numerically and theoretically by many scientists.…”

Measurements of storm and nonstorm circulation in the northern Adriatic: October 2002 Through April 2003

Fifteen bottom‐mounted Acoustic Doppler Current Profilers were deployed from October 2002 through April 2003 in the northern Adriatic Sea. Average transport from the portion of the Western Adriatic Current (WAC) along the Italian slope was 0.1470 ± 0.0043 Sv, punctuated by bursts of more than twice that amount during storm events. Monthly means were calculated with times of strong wind‐driven circulation excluded. These suggest a 2002/2003 seasonal separation consisting of October, December through February, and March through April. An extreme Po River flood influenced November conditions making seasonal categorization difficult. October generally had more kinetic energy and more vertical structure than other months, and near‐inertial waves were more frequent in April and October. The Eastern Adriatic Current (EAC)/WAC (i.e. inflow/outflow) system was clearly present in the means for all months. The cyclonic gyre north of the Po River was present October through February. Generally, in the WAC, over 50% of kinetic energy came from vertically uniform monthly mean flows. Elsewhere, eddy kinetic energy was stronger than mean kinetic energy with 10–40% contributions for vertically uniform monthly mean flows, 40–60% for vertically uniform monthly varying flows, and 10–30% for vertically varying monthly varying flows. Mean currents for bora storms indicate enhancement of the EAC/WAC and the cyclonic northern gyre, a shift toward Kvarner Bay in EAC direction, a circulation null point south of the Po, and double‐gyre bifurcation of flow at Istria. Strengthening of both the EAC and WAC also occurs during sirocco storms.
