Predicting mesoscale variability of the North Atlantic using a physically motivated scheme for assimilating altimeter and Argo observations
A computationally efficient scheme is described for assimilating sea level measured by altimeters and vertical profiles of temperature and salinity measured by Argo floats. The scheme is based on a transformation of ... -
Predicting the frequency of storm surges and extreme sea levels in the northwest Atlantic
[1] A 40 year hindcast of storm surges in the northwest Atlantic and adjacent shelf seas is performed using a 2-D nonlinear barotropic ocean model forced by realistic 6 hourly winds and air pressures. This hindcast is used ... -
Prediction of surface currents and drifter trajectories on the inner Scotian Shelf
The predictive skill of a simple model of surface flow on the Scotian Shelf is assessed using oceanographic data collected in February 1996. The model is forced by wind stress, water density, and sea level along the open ... -
Return periods of extreme sea levels from short records
Extreme sea levels usually arise from a combination of the tides (assumed here to be deterministic) and storm surges (assumed stochastic). The authors show how tide and surge statistics derived from short (~1 year) records ... -
A robust method for diagnosing regional shelf circulation from scattered density profiles
We present a straightforward method for estimating surface circulation on an f plane from a set of irregularly spaced vertical density profiles. The first step is to express bottom density rho(h) as the sum of a mean for ... -
Sea level and circulation variability of the Gulf of Carpentaria; influence of the Madden-Julian Oscillation and the adjacent deep ocean
The Madden-Julian Oscillation (MJO) is a significant contributing factor to intraseasonal variability in both the tropical and extratropical atmosphere and ocean. Sea level and circulation variations in the Gulf of Carpentaria ... -
Subtidal circulation on the Scotian Shelf: assessing the hindcast skill of a linear, barotropic model
Currents measured during the winter of 1985-1986 by four moorings on the inner Scotian Shelf are used to assess the hindcast skill of a three-dimensional circulation model forced by local wind stress and coastal sea level. ... -
Surface heat flux, horizontal advection, and the seasonal evolution of water temperature on the Scotian Shelf
Seasonal temperature variations on the Scotian Shelf penetrate to a depth of about 75 m. The net surface heat flux (Q) can explain about 85% of the annual cycle in the rate of change of mean temperature over this depth ... -
Tide-surge interaction off the east coast of Canada and northeastern United States
[1] Sea level observations and a dynamical model are used to investigate tide-surge interaction in the coastal waters off the east coast of Canada and northern USA. The study is motivated in part by the need to improve ... -

Tropical Pacific Ocean and the Madden-Julian Oscillation: Role of wind and buoyancy forcing
A global ocean circulation model is used to examine the dynamical response of the tropical Pacific Ocean to forcing associated with the Madden-Julian Oscillation (MJO). Model sensitivity experiments first reveal that ...
