2. Presentation of the tools developed (part 1)

3. How do numerical models work? -> Alejandro ORFILA, UIB-IMEDEA Presentation of the tools developed (part 1)

4. What is ocean modelling? The ocean (like the atmosphere) is composed by a (newtonian) fluid that can be -quite well- studied using one some basic laws and a couple of principles…. - F=m·a - Conservation of mass, temperature (energy) Seems feasible …. And forcing, and assimilation….? BUT N-S equations are hyperbolic-type…..so we need, to set up initial conditions

5. (1) Tosca Project is indebted at this point to: Copernico, Archimedes, da Vinci, Torricelli, Pascal, Bernoulli, Newton, Lagrange, Euler, Navier, Stokes and some (not many) others. 19/12/2015 System (Ocean/Atmosphere/.. Dynamical Model Prediction Assimilation Basic Principles (1) Time Integration Exactly!!!... Our problem deals with the lack of And….N/S equations are nonlinear How models work?

Molcard... Ocean modelling + SSH, SST, etc… The TOSCA concept
