The following illustrates the zonal and depth average length scales, Rossby radius (defined as \( \frac{1}{\pi f} \int_H N dz\)) and \( \delta \)-parameter (defined as \( \frac{H_y}{-\rho_y/\rho_z} \), where subscript implies gradient) , associated with each case.
The following three cases (08-10) have the same slopes (75 km wide) and differ only in stratification (Rossby radius defined as \( \frac{1}{\pi f} \int_H N dz\)). The spectra is calculated for years 5-8.
The following three cases (05-07) have the different slopes but similar stratification (mid-channel Rossby radius approximately 10 km). The spectra is calculated for years 4-5.
