  \subsubsection{Numerical Stability Criteria}
+ \label{www:tutorials}
  The Laplacian dissipation coefficient, $A_{h}$, is set to $5 \times 10^5 m s^{-1}$.
  This value is chosen to yield a Munk layer width \cite{adcroft:95},
  \begin{eqnarray}
  \label{EQ:eg-global-munk_layer}
- M_{w} = \pi ( \frac { A_{h} }{ \beta } )^{\frac{1}{3}}
+ && M_{w} = \pi ( \frac { A_{h} }{ \beta } )^{\frac{1}{3}}
  \end{eqnarray}
  \noindent  of $\approx 600$km. This is greater than the model

  parameter to the horizontal Laplacian friction \cite{adcroft:95}
  \begin{eqnarray}

+ && S_{l} = 4 \frac{A_{h} \delta t_{v}}{{\Delta x}^2}
