Inverse Modeling of Ocean Tides
نویسنده
چکیده
The principal long term goal of this project is to develop a practical, portable, nested, tidal data assimilation scheme which makes use of all available data (e.g., altimetry data, current moorings, coastal radar) to constrain barotropic and baroclinic tides (especially tidal currents) in coastal areas and shallow seas. A second long term goal is to develop more efficient methods for assimilation of very large oceanographic data sets.

Enhanced Predictions of Tides and Surges through Data Assimilation (TECHNICAL NOTE)
The regional waters in Singapore Strait are characterized by complex hydrodynamic phenomena as a result of the combined effect of three large water bodies viz. the South China Sea, the Andaman Sea, and the Java Sea. This leads to anomalies in water levels and generates residual currents. Numerical hydrodynamic models are generally used for predicting water levels in the ocean and seas. But thei...

The approach is to incorporate latest developments in turbulence and tidal research and modeling into ROMS. This project complements well, the AESOP program, the ONR DRI on subgrid-scale parameterization and skill assessment of numerical ocean models as well as the new Characterization and Modeling of Archipelago Strait Dynamics (CMASD) DRI. Using the Adriatic Sea (and North Indian Ocean) ROMS/...

[1] A high-resolution hybrid data assimilative (DA) modeling system is used to study barotropic tides and tidal dynamics on the southeast New England shelf. In situ observations include tidal harmonics of 5 major tidal constituents [M2, S2, N2, O1, and K1] analyzed from coastal sea level and bottom pressure gauges. The DA system consists of both forward and inverse models. The former is the thr...
متن کاملAngular momentum of Arctic Ocean tides
Oceanic tidal angular momentum (OTAM) is calculated for the four major tides of the Arctic Ocean, based on the tidal elevations and current velocities from a recent two-dimensional numerical hydrodynamic model. The presented OTAM tables are meant to be complementary to other modeling studies that use satellite altimetry (which cannot observe Arctic Ocean tides because of ice cover and limited s...
