Dispersion relation of internal waves in the western equatorial Pacific Ocean

摘要

Based mainly on TOGA-COARE data, that is , the CTD data from R/V Xiangyanghong No. 5(Pu et al., 1993), the temperature and current data from the Woods Hole mooring and other Deep current data, the layered numerical profiles of buoyancy frequency and mean current components Are figured out. A numerical method calculating internal wave dispersion relqation without background Shear current, used by Fliegel and Hunkins (1975), is improved to be fit for the internal wave equation With mean currents and their second derivatives. The dispersion relations and wave functions of the long Crested internal wave progressing in any direction can be calculated conveniently by using the improved Method.
