The latitude below which the meridional structure of an equatorial gravity or Rossby wave is wavelike and beyond which the meridional structure is decaying.
With the β-plane approximation, the turning latitude (one in each hemisphere) is defined as
With the β-plane approximation, the turning latitude (one in each hemisphere) is defined as
where n is the meridional mode number, c is the phase speed of a given vertical mode Kelvin wave, and β is the derivative of Coriolis parameter f with respect to latitude.
