Accuracy assessment of recent ocean tide models

Creator:: Shum, C. K., Woodworth, P. L., Andersen, O. B., Egbert, Gary D., Francis, O., King, C., Klosko, S. M., Le Provost, C., Li, X., Molines, J-M., Parke, M. E., Ray, Richard D., Schlax, M. G., Stammer, D., Tierney, C. C., Vincent, P., and Wunsch, C. I.
Abstract:: Over 20 global ocean tide models have been developed since 1994, primarily as a consequence of analysis of the precise altimetric measurements from TOPEX/POSEIDON and as a result of parallel developments numerical tidal modeling and data assimilation. This paper provides an accuracy assessment of 10 such tide models and discusses...

Accuracy assessment of global barotropic ocean tide models

Creator:: Stammer, D., Ray, R. D., Andersen, O. B., Arbic, B. K., Bosch, W., Carrère, L., Cheng, Y., Chinn, D. S., Dushaw, B. D., Egbert, G. D., Erofeeva, S. Y., Fok, H. S., Green, J. A. M., Griffiths, S., King, M. A., Lapin, V., Lemoine, F. G., Luthcke, S. B., Lyard, F., Morison, J., Müller, M., Padman, L., Richman, J. G., Shriver, J. F., Shum, C. K., Taguchi, E., and Ti, Y.
Abstract:: The accuracy of state-of-the-art global barotropic tide models is assessed using bottom pressure data, coastal tide gauges, satellite altimetry, various geodetic data on Antarctic ice shelves, and independent tracked satellite orbit perturbations. Tide models under review include empirical, purely hydrodynamic (“forward”), and assimilative dynamical, i.e., constrained by observations. Ten dominant...

The Global S₁ Tide

Creator:: Ray, Richard D. and Egbert, Gary D.
Abstract:: The small S₁ ocean tide is caused primarily by diurnal atmospheric pressure loading. Its excitation is therefore unlike any other diurnal tide; in particular, pressure loading is maximum near the equator where the diurnal gravitational potential is zero. The global character of the S₁ tide is here determined by numerical...

Fortnightly Earth rotation, ocean tides and mantle anelasticity

Creator:: Ray, Richard D. and Egbert, Gary D.
Abstract:: This study of the fortnightly Mf tide comprises three main topics: (1) a new determination of the fortnightly component of polar motion and length of day (LOD) from a multidecade time-series of observed space-geodetic data; (2) the use of the polar motion determination as one constraint in the development of...

Deviation of Long-Period Tides from Equilibrium: Kinematics and Geostrophy

Creator:: Egbert, Gary D. and Ray, Richard D.
Abstract:: New empirical estimates of the long-period fortnightly (Mf) tide obtained from TOPEX/Poseidon (T/P) altimeter data confirm significant basin-scale deviations from equilibrium. Elevations in the low-latitude Pacific have reduced amplitude and lag those in the Atlantic by 308 or more. These interbasin amplitude and phase variations are robust features that are...

The Inverse Ocean Modeling System. Part II: Applications

Creator:: Muccino, J. C., Arango, H. G., Bennett, A. F., Chua, B. S., Cornuelle, B. D., Di Lorenzo, E., Egbert, G. D., Haidvogel, D., Levin, J. C., Luo, H., Miller, A. J., Moore, A. M., and Zaron, E. D.
Abstract:: The Inverse Ocean Modeling (IOM) System is a modular system for constructing and running weak-constraint four-dimensional variational data assimilation (W4DVAR) for any linear or nonlinear functionally smooth dynamical model and observing array. The IOM has been applied to four ocean models with widely varying characteristics. The Primitive Equations Z-coordinate-Harmonic Analysis...

Assimilation of moored velocity data in a model of coastal wind-driven circulation off Oregon: Multivariate capabilities

Creator:: Kurapov, Alexander, Allen, John S., Egbert, Gary D., Miller, Robert N., Kosro, P. Michael, Levine, Murray D., and Barth, John A.
Abstract:: Horizontal current measurements from an array of moored acoustic Doppler profilers are assimilated sequentially into a model of coastal wind-driven circulation off Oregon during the upwelling season of May–August 2001. Model results are compared against independent moored and ship survey data to document a positive effect of velocity data assimilation...

Evaluation of a present-day climate simulation with a new coupled atmosphere-ocean model GENMOM

Creator:: Alder, J. R., Hostetler, S. W., Pollard, D., and Schmittner, A.
Abstract:: We present a new, non-flux corrected AOGCM, GENMOM, that combines the GENESIS version 3 atmospheric GCM (Global Environmental and Ecological Simulation of Interactive Systems) and MOM2 (Modular Ocean Model version 2) nominally at T31 resolution. We evaluate GENMOM by comparison with reanalysis products (e.g., NCEP2) and three models used in...

Poleward propagating subinertial alongshore surface currents off the U.S. West Coast

Creator:: Kim, Sung Yong, Cornuelle, Bruce D., Terrill, Eric J., Jones, Burt, Washburn, Libe, Moline, Mark A., Paduan, Jeffrey D., Garfield, Newell, Largier, John L., Crawford, Greg, and Kosro, P. Michael
Abstract:: The network comprising 61 high-frequency radar systems along the U.S. West Coast (USWC) provides a unique, high resolution, and broad scale view of ocean surface circulation. Subinertial alongshore surface currents show poleward propagating signals with phase speeds of O(10) and O(100–300) km d⁻¹ that are consistent with historical in situ...

Abstract:: The nearly completed U.S. West Coast (USWC) high-frequency radar (HFR) network provides an unprecedented capability to monitor and understand coastal ocean dynamics and phenomenology through hourly surface current measurements at up to 1 km resolution. The dynamics of the surface currents off the USWC are governed by tides, winds, Coriolis...
