Is the viscosity term in this equation? On slide 20, the viscosity term was ρv∇2u, but I don't see it here. Is it already ommitted?

What is the advect function here?

One cool application of the semi-lagrangian advection method is with shallow water equations as shown in this article https://journals.ametsoc.org/view/journals/mwre/116/8/1520-0493_1988_116_1587_aotslm_2_0_co_2.xml. It talks of how using the method with grid-point numerical weather prediction models allows for much larger time steps.

How does the advection function here make the final velocity to be unconditionally stable?
