2.14.8 Vertical dissipation

Currently, this is exactly the same code as the flux form equations.

$\displaystyle G_u^{v-diss}$ $\displaystyle =$ $\displaystyle \frac{1}{\Delta r_f h_w} \delta_k \tau_{13}$ (2.162)
$\displaystyle G_v^{v-diss}$ $\displaystyle =$ $\displaystyle \frac{1}{\Delta r_f h_s} \delta_k \tau_{23}$ (2.163)

represents the general discrete form of the vertical dissipation terms.

In the interior the vertical stresses are discretized:

$\displaystyle \tau_{13}$ $\displaystyle =$ $\displaystyle A_v \frac{1}{\Delta r_c} \delta_k u$ (2.164)
$\displaystyle \tau_{23}$ $\displaystyle =$ $\displaystyle A_v \frac{1}{\Delta r_c} \delta_k v$ (2.165)
