tidal frequency

tidal frequency

[′tīd·əl ′frē·kwən·sē]
(oceanography)
The rate of travel, in degrees per day, of a component of a tide, the component being created by a particular juxtaposition of forces in the sun-earth-moon system.

In (2), A is tidal excursion and it was found that the value of A was less than 10% variation in the measured quantities of this range; the data presented are for A = 20 m; [omega] is the tidal frequency. Another parameter is the height caused by the change in horizontal directional pressure formulated by [mathematical expression not reproducible] sand the Coriolis parameter f = 2[OMEGA].
The parameters used for the evaluation need the inclusion of the tidal force parameter [F.sub.tide] = [rho].sub.0] [Aw.sup.2] sin wt, where A is the tidal excursion; in this case A should be less than the channel width (A = 20 m) [[rho].sub.0] = 1000 kg/[m.sup.3]; v = 0.01 [m.sup.2]/s is kinematic viscosity, tidal frequency (w = [w.sub.M2] = 1.4052 x [10.sup.-4] rad/s), and earth's rotational angle velocity [OMEGA] = 7.29 x [10.sup.-5] and [alpha] = [pi]/3 as the constant geostrophic current velocity.
Similarly, we calculated the average spectrum of the groundwater level of each observation well for the same tidal frequency at different times.
Tidal frequency internal waves, generated by barotropic tidal flow over topographic obstacles in a stably stratified fluid, lead to local mixing near the generation site, both due to direct wave breaking (close to topography) and enhanced rates of interaction with other internal waves (well above topography).
At and just below a critical latitude where the Coriolis frequency is half the tidal frequency, particularly efficient wave-wave interactions of a parametric subharmonic instability type lead to a dissipation profile with high values extending several hundred meters above the bottom, before decaying rapidly to background levels, and q > 0.4 (MacKinnon and Winters 2003; Ivey et al.
The conclusion from our analysis is that we have unambiguously detected the residual oscillations in tidal frequency bands.
This pattern of release minimizes the impact of visual predators on newly hatched zoeae and takes advantage of circulation at tidal frequency to transport zoeae away from intertidal habitats where conditions may not be favorable for larval development.
This pattern of release also takes advantage of circulation at tidal frequency to transport zoeae away from intertidal habitats where conditions may not be conducive to larval development.
This consists of upward migration during nocturnal flood tides, which allows megalopae to take advantage of circulation at tidal frequency to facilitate further transport up the estuary (Tankersley & Forward 1994, Tankersley et al.
