-\subsubsection{Numerical Stability Criteria}
-\label{www:tutorials}
-
-The Laplacian dissipation coefficient, $A_{h}$, is set to $400 m s^{-1}$.
-This value is chosen to yield a Munk layer width \cite{adcroft:95},
-
-\begin{eqnarray}
-\label{EQ:eg-baro-munk_layer}
-M_{w} = \pi ( \frac { A_{h} }{ \beta } )^{\frac{1}{3}}
-\end{eqnarray}
-
-\noindent  of $\approx 100$km. This is greater than the model
-resolution $\Delta x$, ensuring that the frictional boundary
-layer is well resolved.
-\\
-
-\noindent The model is stepped forward with a 
-time step $\delta t=1200$secs. With this time step the stability 
-parameter to the horizontal Laplacian friction \cite{adcroft:95}

-\begin{eqnarray}
-\label{EQ:eg-baro-laplacian_stability}
-S_{l} = 4 \frac{A_{h} \delta t}{{\Delta x}^2}
-\end{eqnarray}
-
-\noindent evaluates to 0.012, which is well below the 0.3 upper limit
-for stability.

-\begin{eqnarray}

-S_{i} = f^{2} {\delta t}^2
-\end{eqnarray}

-limit for stability.

-horizontal flow speed of $ | \vec{u} | = 2 ms^{-1}$

-S_{a} = \frac{| \vec{u} | \delta t}{ \Delta x}

-of 0.5 and limits $\delta t$ to $1200s$.
