r11336 r11386 399 399 A_l = \left\{ 400 400 \begin{aligned} 401 & \frac{ \max(e_1,e_2)}{e_{ref}} A_o^l& \text{for laplacian operator } \\402 & \frac{ \max(e_1,e_2)^{3}}{e_{ref}^{3}} A_o^l& \text{for bilaplacian operator }401 & \frac{1}{2} U_{scl} \max(e_1,e_2) & \text{for laplacian operator } \\ 402 & \frac{1}{12} U_{scl} \max(e_1,e_2)^{3} & \text{for bilaplacian operator } 403 403 \end{aligned} 404 404 \right. 405 405 \end{equation} 406 where $e_{ref}$ is a reference grid size harcoded to a $1^{\circ}$ grid size (\ie $e_{ref}\approx 111 km$), 407 and $A_o^l$ is the user defined mixing coefficient defined according to \autoref{eq:constantah}. 406 where $U_{scl}$ is a user defined velocity scale (\np{rn\_Ud}, \np{rn\_Uv}). 408 407 This variation is intended to reflect the lesser need for subgrid scale eddy mixing where 409 408 the grid size is smaller in the domain.
