Atmospheric forcing of the oceanic semidiurnal tide
[1] The principal solar semidiurnal tide (S2) in the ocean is forced by the pressure loading of the atmospheric thermal tide as well as by the gravitational tidal potential. This paper examines the effects of adding the atmospheric S2 forcing to a forward tide model. When the model is forced only by the gravitational potential, the S2 relative elevation error with respect to pelagic tide gauges...
متن کاملSemidiurnal internal tide incoherence in the equatorial Pacific
The jets in the equatorial Pacific Ocean of a realistically forced global circulation model with a horizontal resolution of 1=12:5 cause a strong loss of phase coherence in semidiurnal internal tides that propagate equatorward from the French Polynesian Islands and Hawaii. This loss of coherence is quantified with a baroclinic energy analysis, in which the semidiurnal-band terms are separated i...
متن کاملThe lunar tide in sporadic E
It seems that the wind shear theory is accepted for the explanation of sporadic E at mid and low latitudes. Some examples from Arecibo are displayed to show this. The eect of lunar tides should then modify the wind-shear theory in a manner that yields the observed features of the lunar tide in the critical frequency foEs and the height h¢Es of the sporadic E. This is shown to imply that the ph...
متن کاملA link between variability of the semidiurnal tide and planetary waves in the opposite hemisphere
Horizontal wind observations over four years from the meteor radar at Esrange (68 ̊N) are analyzed to determine the variability of the semidiurnal tide. Simultaneous global observations of temperature and geopotential from the SABER satellite instrument are used to construct time series of planetary wave amplitudes and geostrophic mean zonal wind. During NH summer and fall, the temporal variabil...
متن کاملA new perspective on the longitudinal variability of the semidiurnal tide
[1] The longitudinal variability of the semidiurnal tide in the Antarctic upper mesosphere is investigated by comparison of observations from two radars at approximately opposite sides of Antarctica. Under the assumption that the tide is composed of an S = 2 (migrating) and S = 1 (westward‐ propagating, non‐migrating) component only, the relative phases of the components are shown to vary with ...
