We describe a simple classroom demonstration of a fluid-dynamic instability. The demonstration requires only a bucket of water, a piece of string and some used tealeaves or coffee grounds. We argue that the mechanism for the instability, at least in

The importance of oceans for atmospheric forecasts as well as climate simulations is being increasingly recognised with the advent of coupled ocean / atmosphere forecast models. Having comparable resolutions in both domains maximises the benefits for

The aim of the work reported in this article is to provide new insights into the dynamics and instabilities of a barotropic shear layer in a rotating fluid. Above a critical value of horizontal stress, the flow within a bounded system in rotation is

International audience; The stability of circular vortices to normal mode perturbations is studied in a multi-layer quasi-geostrophic model. The stratification is fitted on the Gulf of Cadiz where many Mediterranean Water (MW) eddies are generated. O

International audience; We describe surface anticyclones developing in summer time after persistent Levanter (i.e., easterly) gap winds in the Gulf of Cadiz. The process of generation of these eddies is similar to those formed in the tropical Pacific

Dipolar vortex in an anticlockwise rotating platform. The mean depth is 0.85 m and the rotating period of the system is 30 s. The radius of the visible cyclonic part is 0.80 m. The anticyclonic part is formed due to potential vorticity conservation a
