Abstract: | The Laplace tidal equation which plays a basic role in tide theory is investigated. A method of numerically-analytic integration of the Laplace tidal equation over the entire sphere without using the β-plane approximation is developed and its nonaxisymmetric solutions are investigated. Harmonics corresponding to long-period oscillations known as planetary or Rossby waves are obtained. |
