“…It is desirable for the discrete solution to satisfy the analogous conservation property. This is because the weak instability caused by the nonlinear convection term can be avoided if the discrete convection form satisfies this conservation property and the usual CourantFriedrichs-Lewy number condition for linearized stability [26]. Now let us focus only on the spatial discretization and consider the semi-discrete evolution equation as…”

“…The time-differencing scheme is less diffusive than the leapflog approach, based on a square wave test. The approach is referred to as "angled derivative" [Roberts and Weiss, 1966] and has also been investigated by Piacsek and Williams [1970]. Even in the extreme square-wave test, the numerical diffusion is less than half the minimum explicit dif- …”

“…The results presented here are obtained using the Boussinesq equations and a first-order Richardson-number-dependent mixing-length turbulence closure scheme. The secondorder-accurate scheme of Piacsek and Williams (1970) is used for advection of both velocity and potential temperature. A no-slip condition is imposed at the lower boundary (via a similarity condition for the surface stress), along with a zero-surface-heat-flux condition, and the Coriolis force is imposed with f = 10 −4 s −1 .…”
