Surface plots of data

The default quantity to display is the salinity, or s, in planview, at level 1 and time step 1. Color axes are scaled to the minimum and maximum of the profile being shown. They may also be specified by parameters in suntans.dat, as described in Section 8.10. The following buttons control their respective plots: : Salinity Left button: Displays the salinity $s$.

• Middle button: Displays the salinity anomoly $s-s_0$.
• Right button: Displays the background salinity $s_0$.
• : Temperature Left button: Displays the temperature $T$.
  • Middle button: No effect.
  • Right button: No effect.
• : Nonhydrostatic pressure Left button: Displays the nonhydrostatic pressure $q$.
  • Middle button: No effect.
  • Right button: No effect.
• : Free surface Left button: Displays the free surface $h$.
  • Middle button: No effect.
  • Right button: No effect.
• : Eddy viscosity Left button: Displays the eddy viscosity $\nu_t$ at the center of the cell.
  • Middle button: No effect.
  • Right button: No effect.
• : Scalar diffusivity Left button: Displays the scalar diffusivity $\kappa_t$ at the center of the cell.
  • Middle button: No effect.
  • Right button: No effect.
• : Left button: Displays the horizontal cartesian velocity component $u$, at the center of the cell.
  • Middle button: No effect.
  • Right button: Displays the horizontal cartesian baroclinic velocity component $u_b$, at the center of the cell. This is calculated with
    
    $$u_b = u - \frac{1}{D}\int_{-D}^h u dz .$$
    
    

• : Left button: Displays the horizontal cartesian velocity component $v$, at the center of the cell.
  • Middle button: No effect.
  • Right button: Displays the horizontal cartesian baroclinic velocity component $v_b$, at the center of the cell. This is calculated with
    
    $$v_b = v - \frac{1}{D}\int_{-D}^h v dz .$$
    
    

• : Left button: Displays the vertical cartesian velocity component $w$, at the center of the cell.
  • Middle button: No effect.
  • Right button: No effect.
• : Left button: Displays the depth d beneath the 0 datum.
  • Middle button: No effect.
  • Right button: Displays the water depth $h+d$.
• : Left button: No surface plot is shown. Useful for only showing vector field.
  • Middle button: No effect.
  • Right button: No effect.
