Mesoscale Circulations and Surface Energy Balance During Snowmelt in a Regional Climate Model
Mesoscale Circulations Surface Energy Balance Regional Climate Model
2009/10/22
The Canadian Regional Climate Model has recently been coupled with an
advanced, second generation land surface model - the Canadian Land Surface
Scheme. In addition, high resolution land cover and s...
A Quasi-Linear Model of the Combined Wind-Driven and Thermohaline Circulations in a Rectangular β-Plane Ocean
Quasi-Linear Model Thermohaline Circulations Combined Wind-Driven Rectangular β-Plane Ocean
2009/3/24
Three-dimensional temperature and velocity fields are calculated analytically for a rectangular β-plane ocean model, forced by a prescribed wind stress and surface heat flux. A basic thermal state inv...
Verification of Numerical Models of Lake Ontario. II. Stratified Circulations and Temperature Changes
Verification of Numerical Models Lake Ontario Temperature Changes
2009/3/24
Data from the 1972 International Field Year on Lake Ontario are used to test the performance of three-dimensional hydrodynamic models of large lakes. This study is a sequel to a previous report concer...
INTERACTION BETWEEN VARIABLE SOLAR UV RADIATION AND TROPOSPHERIC CIRCULATIONS AS A POSSIBLE CAUSE OF FIVE YEAR OSCILLATION IN EARTH ROTATION
VARIABLE SOLAR UV RADIATION TROPOSPHERIC CIRCULATIONS EARTH ROTATION
2009/3/16
It is shown that Five Year Oscillation in Earth rotation is possibly
caused by variable solar UV radiation and a corresponding perturbation mechanism
is suggested.
Three-Layer Circulations in Estuaries and Harbors
Three-Layer Circulations Estuaries Harbors
2009/3/7
A theory is developed for the three-layer circulation in an overmixed estuary (finite fresh-water influx) or harbor (zero fresh-water influx) accompanying a two-layer structure in the large body of wa...
Mesoscale (50–100 km) Circulations Revealed by Inverse and Classical Analysis of the JASIN Hydrographic Data
Mesoscale (50–100 km) Circulations Inverse JASIN Hydrographic Data
2009/2/5
Inverse analysis (Wunsch, 1978) has been applied to two 10-day surveys of an area 15 km consisting of nearly 100 CTD stations, in order to determine the velocity field with a horizontal resolution of ...
Laboratory Studies of Langmuir Circulations
Langmuir Circulations Laboratory studies crossed waves wind-induced shear
2009/1/22
Laboratory studies of the interaction of crossed waves (on water) and a wind-induced shear are found to be in quite general agreement with the Craik-Leibovich (CL) theory of Langmuir circulation (LC's...
The Fine-Structure of Nearshore Tidal and Residual Circulations Revealed by H.F. Radar Surface Current Measurements
Ocean Surface Current Radar Residual Circulations Nearshore Tidal
2009/1/7
Using the Ocean Surface Current Radar (OSCR) developed by the Rutherford–Appleton Laboratory (UK), 30 days of synoptic hourly surface current vectors were obtained for 84 locations within a nearshore ...
The Roles of Langmuir Circulations in the Dispersion of Surface Tracers
Langmuir Circulations Dispersion of Surface Tracers
2009/1/6
A hierarchy of theoretical and numerical models for the dispersion of discrete floating tracers on lakes and oceans is presented. Central to these models is the role of Langmuir circulations, which co...
On the Catalytic Role of High Baroclinic Modes in Eddy-driven Large-Scale Circulations
Catalytic Role High Baroclinic Modes Eddy-driven Large-Scale Circulations
2008/12/24
This paper investigates the tridimensional consistency of the resolution of eddy scales in simulating large-scale flows. The generation of classical wind-forced, eddy-driven double-gyre circulation is...
Langmuir Circulations in a Surface Layer Bounded by a Strong Thermocline
Langmuir Circulations Surface Layer Bounded Strong Thermocline
2008/12/18
Langmuir circulations reside in, and are responsible in part for the existence and maintenance of, the mixed layer. It is, therefore, typical for the water containing Langmuir circulations to be bound...
Residual Circulations Due to Bottom Roughness Variability under Tidal Flows
Tidal Flows nonlinear interaction residual circulation flows
2008/12/16
Tidal flows over irregular bathymetry are known to produce residual circulation flows due to nonlinear interaction with gradients of depth. Using the depth-averaged vorticity equations, the generation...
