Investigation of main current system and equatorial planetary wavesin the tropical Pacific by action of climatic average wind field

  • The current field was calculated on the basis of the coupling model of a two-layer, reduced gravity primitive equation and the climatic average wind field. The result correctly shows space distribution and season variety of the main current system and thermocline of upper layer in the tropical Pacific. The mixed Rossby-gravity waves were excited by meridional wind stress on 125°W equatorial Pacific. In the climatic condition, the equatorial Kelvin wave current model could be transported from the western equatorial Pacific border to the eastern border, but the equatorial Kelvin wave thermocline model was not, because it was prevented by the westward thermocline perturbation which was excited by mixed Rossby-gravity in the central equatorial Pacific.
