Open Ocean Modeling as an Inverse Problem：Tidal Theory
Open Ocean Modeling Inverse Problem Tidal Theory
2009/2/8
Classical models of tides in open coastal regions employ ad hoc conditions on the open boundaries instead of reliable sea level data on the coastline in order to achieve a well-posed problem. A weight...
Estimation of Low-Frequency Wind Stress Fluctuations over the Open Ocean
Low-Frequency Wind Stress Fluctuations Open Ocean
2009/2/5
A simple, approximate formula for mean wind stress is given in terms of the mean and variance of the wind fluctuations over the averaging period. The formula is nonlinear with respect to the mean wind...
Pressure Fluctuations on the Open-Ocean Floor off the Gulf of California：Tides, Earthquakes, Tsunamis
Pressure Fluctuations Tides Earthquakes Tsunamis Open-Ocean Floor
2009/2/5
This paper supplements an initial article on sea-floor pressure observations conducted with a sensitive though not “perfectly” stable transducer. A variety of examples are used to demonstrate that a w...
Steady wind-drift currents in a deep viscous rotating ocean are studied theoretically. The analysis is based on the Lagrangian description of motion.
A mean wind-stress at the surface yields the tr...
Open Ocean Modeling as an Inverse Problem：M2 Tides in Bass Strait
Open Ocean Modeling Inverse Problem M2 Tides
2009/1/19
The solution of a linear model of barotropic M2 tides in Bass Strait is not consistent with new high quality tide gage and current meter data. This is attributed to the method used to estimate the for...
Toward the Application of the Kalman Filter to Regional Open Ocean Modeling
Kalman Filter Regional Open Ocean Modeling
2009/1/10
As ocean models improve, assimilation of data with the help of models becomes increasingly important. The Kalman filter provides a method for assimilation of data that are arbitrarily distributed in t...
Hindcasting and Forecasting of the POLYMODE Data Set with the Harvard Open–Ocean Model
POLYMODE Data Set Harvard Open–Ocean Model regional quasi-geostrophic model
2008/12/30
A regional quasi-geostrophic model has been used to hindcast and forecast the POLYMODE data set. After briefly discussing hindcast methodology, the hindcast fields are compared with the analyzed data ...
Data Assimilation in a Quasi-geostrophic Open-Ocean Model of the Gulf Stream Region Using the Adjoint Method
quasi-geostrophic Gulf Stream Region Quasi-geostrophic Open-Ocean Model
2008/12/23
The method of adjoint data assimilation is applied in a quasi-geostrophic (QG) open-ocean model of the Gulf Stream region. The results of data assimilation experiments are presented in which simulated...
A Study of Wind Stress and Heat Flux over the Open Ocean by the Inertial-Dissipation Method
Wind Stress Heat Flux Open Ocean Inertial-Dissipation Method
2008/12/19
A bow-mounted propeller anemometer and fast-response temperature sensors were operated during several cruises of CSS Dawson. Spectra of wind speed and temperature fluctuations were measured over the o...
A Heton Model of the Spreading Phase of Open-Ocean Deep Convection
Heton Model Open-Ocean Deep Convection cold water
2008/12/18
A point-vortex heton model of the lateral dispersion of cold water formed in open-ocean deep convection is developed and studied as an idealized representation of the sinking and spreading phase of op...
Convection with Rotation in a Neutral Ocean：A Study of Open-Ocean Deep Convection
Neutral Ocean Open-Ocean Deep Convection Numerical simulations
2008/12/18
The intensity and scale of the geostrophically adjusted end state of the convective overturning of a homogeneous rotating ocean of depth H at a latitude where the Coriolis parameter is f, induced by s...
Heat Flux Partitioning in Open-Ocean Convection
Heat Flux Partitioning Open-Ocean Convection
2008/12/12
Cold air blowing out over a warm ocean leads to convection over an isolated region of the ocean basin. This phenomenon, known as open-ocean convection, is often simulated by convective forcing from a ...
A Heton Perspective of Baroclinic Eddy Transfer in Localized Open Ocean Convection
Eddy Transfer surface buoyancy loss horizontal variations
2008/12/10
A simple point-vortex “heton” model is used to study localized ocean convection. In particular, the statistically steady state that is established when lateral buoyancy transfer, effected by baroclini...
Topographic Preconditioning of Open-Ocean Deep Convection
Topographic Preconditioning Open-Ocean Deep Convection
2008/12/10
Evidence for oceanic convection over Maud Rise in the Weddell Sea suggests that bottom topography may select the location and scale of deep convecting oceanic chimneys forced by seasonal large-scale a...
Wind Stress Measurements from the Open Ocean
Wind Stress Measurements Open Ocean automatic inertial dissipation system
2008/12/9
An automatic inertial dissipation system was used during three cruises of the RRS Discovery in the Southern Ocean to obtain a large dataset of open ocean wind stress estimates. The wind speed varied f...
