    Notes: Abstract Geopotential values ―W of the mean equipotential surfaces representing the mean ocean topography were computed on the basis of four years (1993 - 1996) TOPEX/POSEIDON altimeter data: ―W = 62 636 854.10m 2 s −2 for the Pacific (P), ―W = 62 636 858.20m 2 s −2 for the Atlantic (A), ―W = 62 636 856.28m 2s−2 for the Indian (I) Oceans. The corresponding mean separations between the ocean levels were obtained as follows: A − P = − 42 cm, I− P = − 22 cm, I − A = 20 cm, the rms errors came out at about 0.3 cm. No sea surface topography model was used in the solution.

    Notes: Abstract The T/P altimeter data 1993 – 1997 (cycles 11 – 194) has been analyzed with emphases on seasonal variations in sea surface topography (SST). The amplitude of the annual variations amounted to (5.9±0.3) mm when inverted barometer (IB) corrections were applied and (2.0±0.4) mm without any IB corrections. The amplitude of the semi-annual variations in SST was small with IB corrections applied: (0.6±0.3) mm. However, when no IB corrections were applied, it was (1.8±0.4) mm, i.e. the semiannual variations are at the same level as the annual variations with no IB corrections. The phase angle offset of the annual term has shifted by about 180° when IB correction was applied. The dynamics of the ocean-atmosphere system is discussed and it is concluded that it could, at least partly, be responsible for the above observed effects.
