O1, P1, N2 models of the global ocean tide on an elastic earth plus surface potential and spherical harmonic decompositions for M2, S2, and K1

摘要

Because of the growing utility of having models of additional tidal constituents, this paper supplements models of M2, S2, and K1 presented previously in this journal with models of O1, P1, and N2 produced in exactly the same way. As before, the models satisfy specified elevation boundary conditions and are generated by fitting a small number of test functions to island data. Having models of three constituents in each band allows for estimates of cross#x2010;band variations. Model admittances vary smoothly from place to place throughout the deep oceans, although significant variations can occur over distances as short as a few thousand kilometers; the most significant variations occur in the South Atlantic and Pacific oceans.
