Abstract:
By using a linear oceanic mixed layer model, the long period waves in the tropical ocean are investi-gated numerically. Due to the inhomogeneity of the large-scale average sea temperature field of the ocean in tropical regions, besides the westward propagating equatorial Rossby wave to be modified, there will be a kind of long period thermal wave which propagates eastward under certain oceanic background conditions. Under the influences of these two kinds of waves, the propagating and evolving processes of the sea surface temperature anomalies (SSTA) are dearly shown by numerical experiments. The results of numerical ex-periments are consistent with the ones obtained by the theoretical analysis in Part I. The possible relation-ship between these two kinds of waves and El Nino events is also discussed indirectly.
