Design is optimised for various suggested meridional velocity distributions.

A parameter representing the damping associated with meridional velocity gradients has very little effect on the solution and could be set to zero.

Standard state variables were calculated including temperature, salinity, zonal and meridional velocities, and sea level, as well as several derived fields such as heat content.

The governing equations for these equatorial waves are similar to those presented above, except that there is no meridional velocity component (that is, no flow in the north-south direction).
