S. Pierini is coordinating the 19GAPWEBS project within the EU’s Horizon 2020 Hydralab+ (n. 654110). The project is aimed at simulating gap-leaping and intruding western boundary currents by means of the large Coriolis Rotating Platform at the Laboratoire des Écoulements Géophysiques et Industriels (LEGI-CNRS, Grenoble).

The Coriolis platform, 13 m in diameter, is the largest rotating platform in the world dedicated to fluid dynamics. Its main activity is the experimental modeling of geophysical flows, taking into account the rotation of the Earth, in the presence or not of density stratification or topography. The large size provides access to the inertial regimes that characterize ocean dynamics, with little influence of viscosity and centrifugal force. Laboratory experiments can thus provide support to model ocean dynamics and develop their physical parameterizations.

The facility is equipped, among other instruments, with the Particle Imaging Velocimetry (PIV) system, which provides time resolved velocity fields in both horizontal and vertical planes of up to 3 m x 4 m in size, with a relative precision 2%. The laser sheet position is scanned by a computer controlled system, so that image correlation for PIV can be made in a volume. Both vorticity and divergence fields can be computed from the PIV data and directly compared with numerical computations.
