On stochastic stability of regional ocean models with uncertainty in wind forcing
stochastic stability regional ocean models uncertainty in wind forcing
2009/11/3
A shallow-water model was used to understand model error induced by non-Gaussian wind uncertainty. Although the model was simple, it described a generic system with many degrees of freedom randomized ...
Deep Water Exchanges in a Sill Fjord：A Stochastic Process
Deep Water Exchanges Sill Fjord Stochastic Process
2009/4/2
A statistical theory for the behavior of a fjord system with a sill is formulated and leads to the establishment of conditional and marginal distribution functions for the homogeneous deep water densi...
The Noutidal Flow in the Providence River of Narragansett Bay：A Stochastic Approach to Estuarine Circulation
Noutidal Flow Narragansett Bay Providence River Estuarine Circulation
2009/3/7
Atmospherically driven flow in the Providence River (a partially mixed estuary) has been examined using a 51-day velocity record measured 2 m from the bottom. Velocity fluctuations at time scales betw...
Stochastic Form of the Growth of Wind Waves in a Single-Parameter Representation with Physical Implications
Wind Waves Single-Parameter Representation Physical Implications
2009/2/23
It is shown that a simple relation, E* = 5.1 × 10−2 σm*−3 for describing the conditions of growing wind waves, is supported by various available data, where E* = g2E/u*4 is dimensionless e...
Stochastic analysis of a three unit standby system

2009/2/19
This paper presents a stochastic analysis of a non-identical three-unit system
with one-unit as standby and the other two units online by a Graphical
Evaluation and Review Technique (GERT). In this ...
Stochastic Dynamic Analysis of Polar Sea Ice Variability
Polar Sea Ice Variability Stochastic Dynamic Analysis
2009/2/19
The analysis of Arctic (1966–76) and Antarctic (1973–79) sea ice data is presented, and a dynamical model based on white noise atmospheric forcing, local stabilizing relaxation and lateral diffusion a...
Quasi-Geostrophic Response of an Infinite β-Plane Ocean to Stochastic Forcing by the Atmosphere
Quasi-Geostrophic Stochastic Forcing Infinite β-Plane Ocean
2009/2/11
The quasi-geostrophic response of the ocean to stochastic forcing by wind stress and atmospheric pressure is investigated using a linear, continuously stratified, β-plane oceanic model with a flat bot...
Coastal Upwelling Viewed as a Stochastic Phenomenon
Coastal Upwelling Stochastic Phenomenon
2009/1/21
Four years of winds from the northeastern Pacific are used to drive a reduced-gravity ocean model which includes a high-resolution eastern coastal zone that span 17° longitude and 30° latitude. Spectr...
Stochastic Wind Forcing of Baroclinic Rossby Waves in the Presence of a Meridional Boundary
Stochastic Wind Forcing Baroclinic Rossby Waves Meridional Boundary
2009/1/15
The quasigeostrophic response of a continuously stratified ocean to a band-limited white-noise windstress curl is examined in an infinite and semi-infinite ocean. Baroclinic Rossby waves—predominantly...
Oceanic Quasi-geostrophic Turbulence Forced by Stochastic Wind Fluctuations

2009/1/7
The quasi-geostrophic response to stochastic wind fluctuations is calculated using a doubly periodic nonlinear model, with a vertical resolution of three modes in most cases. The influence of various ...
Stochastic Wave Radiation by the Gulf Stream

2009/1/6
A linear, small amplitude model of Rossby waves forced by idealized meanders is presented in order to ascertain whether or not the observed low frequency motions near the Gulf Stream are capable of be...
A Simple Model of the Decadal Response of the Ocean to Stochastic Wind Forcing
