A set of numerical experiments is presented, in which we study the dynamics of passive particles advected by given two-dimensional velocity fields and perturbed by a non-white noise with a characteristic time τ. Data and model results have shown

This paper is concerned with a fundamental marineproblem, i.e. the internal waves. After a discussion of the physical assumptionsabout some mathematical models describing the vertical structureof the sea, we present the various driving forces and the

We study some explicit cases of marine thermocline. We focus our attention on the strongly vertically trapped internal waves, which in our cases allow an explicit dispersion relation and a simple behaviour in terms of elementary functions. The exp

The present note deals with Munk's ocean model and proposes an alternative approach to find its solution, with special regard to the western boundary layer. We introduce a suitable "distance" between the related Sverdrup streamfunction and all the ad

Quasi-geostrophic potential-vorticity equations in the inertial regime are obtained by eliminating the ageostrophic vertical velocity from two coupled equations: a vorticity equation and a local conservation equation which depends on special properti

Data collected by the Institute of Atmospheric Physics of CNR (Italy) during the 1991 Italian Antarctic expedition are used for the development of Earth-air-sea interaction studies. In this paper wind and temperature data obtained by a digitized ultr

A potential-vorticity-conserving, channelled flow is investigated in the presence of a step-like cross-stream topography, in order to simulate the behaviour of an idealized coastal current. This is performed by resorting to a truncated perturbative e

In the framework of the quasi-geostrophic fluid dynamics, we investigate the distinctive condition which leads to the linear or, alternatively, to the nonlinear quasi-geostrophic potential-vorticity equations at the ocean basin-scale. In most of the
