The steady state flow of water through unsaturated soil in the low capillary potential region

Creator:: Stammers, William Norman
Abstract:: Several investigators have recently called attention to the fact that the flux equation for water movement in unsaturated soils may not be an appropriate mathematical model for the development of the theory of unsaturated flow phenomena. An analytical theory is developed for the purpose of testing the validity of the...

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.

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...

Un Paseo encantado

Creator:: Joyner, Taylor B.
Abstract:: Un Paseo Encantado, an enchanted walk, is a collection of my observations and experiences in a study abroad program in Oviedo, Spain. My commentary on Spanish culture is based on reading I did prior my departure, in combination with my observations while in Spain. In six chapters, I explore the...

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...
