“…The main harmonics observed amplitudes and phases were estimated by Vercelli (1925) during the homonym oceanographic cruise in 1922 and more recently reported by Brandolini et al (1980) and Androsov et al (2002a). In this work we refer to the values from Brandolini et al (1980) for stations from 1 to 6 and from Androsov et al (2002a) for stations from 7 to 10. We considered the tidal signals as composed by four semidiurnal waves (M2, S2, N2 and K2), by three diurnal waves (K1, O1 and P1) and by the M4 as compound tide, which are the major components of the tides in the Mediterranean Sea and in the MS (Vercelli, 1925;Sannino et al, 2014).…”

“…Although notorious, the dynamic of the Strait is not fully addressed in scientific literature, with only few and old studies describing the water circulation in both theoretical and experimental terms (Hopkins et al, 1984;Cescon et al, 1997) and very few recent investigations using numerical modelling techniques (Androsov et al, 2002a, b). In particular, while tidal dynamic inside the Strait has been studied and described by many authors starting from the early XX century (Vercelli, 1925(Vercelli, , 1926Defant, 1940Defant, , 1961Bossolasco and Dagnino, 1957;Massi and Sallusti, 1979;Mosetti, 1988), the effects of the Messina tidal in-and outflow on the outer open ocean thermohaline water circulation are still unaddressed in scientific literature.…”

In particular, both recent and old studies focused mainly on describing the behaviour of Tyrrhenian and Ionian waters flowing through the Strait (Bossolasco and Dagnino, 1959;Androsov et al, 2002b) and on the gener- ation of internal waves (Brandt et al, 1997(Brandt et al, , 1999 without quantifying the role of MS tidal dynamics in modifying the outer circulation pattern.…”

Abstract. This work explores the importance of considering tidal dynamics when modelling the general circulation in the Messina Strait, a narrow passage connecting the Tyrrhenian and the Ionian subbasins in the Western Mediterranean Sea. The tides and the induced water circulation in this Strait are among the most intense oceanographic processes in the Mediterranean Sea. The quantification of these effects can be particularly relevant for operational oceanographic systems aimed to provide short-term predictions of the main hydrodynamics in the Western Mediterranean subbasins. A numerical approach based on the use of a high-resolution hydrodynamic model was followed to reproduce the tides propagation and the wind-induced and thermohaline water circulation within the Strait and in surrounding areas. A set of numerical simulations was carried out to quantify the role of the Strait dynamics on the larger-scale water circulation. The obtained results confirmed the importance of a correct representation of the hydrodynamics in the Messina Strait even when focusing on predicting the water circulation in the external sea traits. In fact, model results show that tidal dynamics deeply impact the reproduction of the instantaneous and residual circulation pattern, waters thermohaline properties and transport dynamics both inside the Messina Strait and in the surrounding coastal and open waters.

“…Because of these particular environmental features, the Straits have been studied by many researchers in order to define forcing factors that determine its current regimen (cf., Vercelli, 1925;Vercelli and Picotti, 1926;Defant, 1940;Del Ricco, 1982;Tomasin and Tomasino, 1983;Böhm et al, 1987;Mosetti, 1988;Androsov et al, 1994;Androsov et al, 2002). Many hydrobiological studies have been conducted over the last few decades to describe the influence of complex hydrodynamic conditions on biological parameters (De Domenico, 1987;Bruni et al, 1988;Genovese et al, 1984;De Domenico et al, 1988;Magazzù et al, 1987;1989;Decembrini et al, 1998;Azzaro et al, 2004a;2004b).…”

Seasonal variability of phytoplankton fluorescence in relation to the Straits of Messina (Sicily) tidal upwelling

et al. 2007

Abstract. In the Straits of Messina, large gradients of tidal displacements, as well as the topographic constrictions, determine the upwelling of deeper waters in the surface layer. This work describes the seasonal variability in the surface distribution of phytoplankton biomass depending on the upwelling phenomena. Temperature, salinity, nitrates and phytoplankton fluorescence were measured in 1994 and 1995 by continuous underway surface real-time measurements onboard dedicated research boats. Each survey was performed following the dynamic phases of flooding and ebbing tides. Tidal currents are essentially southward during high tide and northward during low tide.During the low water slack tide, large spatial gradients of physical-chemical and biological parameters were found, while at the high water slack tide, a diffused phytoplankton fluorescence was observed only in autumn due to a seasonal thermocline. Salinity, nitrate and chlorophyll-a fluorescence data revealed a significant positive intercorrelation, whereas they were inversely correlated with temperature. Generally, the upwelling distribution was limited to narrow zones during winter, while in summer it was found in the middle of the Straits and in the southern zones. During spring in the southern zone of the Straits, the maximum chlorophyll-a fluorescence was detected (May 1995, 0.32 µg-Chla l −1 ); in summer, when back and forth tidal movements between the Tyrrhenian and the Ionian seas intensify, decreased values were observed throughout the study area.The data set obtained through continuous and repeatable samplings has allowed the study of different time-space scales in the Straits of Messina, a very strong and dynamic environment.The Straits system could be compared to an "intermittent pump" which, during the different seasons, initially enriches itself and subsequently provides nutrients to the surrounding basins.

An efficient curvilinear non‐hydrostatic model for simulating surface water waves

An efficient curvilinear non‐hydrostatic free surface model is developed to simulate surface water waves in horizontally curved boundaries. The generalized curvilinear governing equations are solved by a fractional step method on a rectangular transformed domain. Of importance is to employ a higher order (either quadratic or cubic spline function) integral method for the top‐layer non‐hydrostatic pressure under a staggered grid framework. Model accuracy and efficiency, in terms of required vertical layers, are critically examined on a linear progressive wave case. The model is then applied to simulate waves propagating in a canal with variable widths, cnoidal wave runup around a circular cylinder, and three‐dimensional wave transformation in a circular channel. Overall the results show that the curvilinear non‐hydrostatic model using a few, e.g. 2–4, vertical layers is capable of simulating wave dispersion, diffraction, and reflection due to curved sidewalls.
