Tide-surge interaction off the east coast of Canada and northeastern United States
(2007-06)
[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 ...
The mean surface circulation of the North Atlantic subpolar gyre: A comparison of estimates derived from new gravity and oceanographic measurements
(2011-08)
A new mean sea surface topography (MSST) is used to estimate the surface circulation of the subpolar gyre of the northwest Atlantic. The MSST is produced using a new geoid model derived from a blend of gravity data from ...
Predicting the frequency of storm surges and extreme sea levels in the northwest Atlantic
(2006-10)
[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 ...
A description of water types on the Mackenzie Shelf of the Beaufort Sea during winter
(1992)
For a number of years during the 1980s, observations of the physical and chemical properties of seawater in the southeastern Beaufort Sea have been acquired in late winter. The most complete data set, from 1987, has been ...
Madden-Julian Oscillation and sea level: Local and remote forcing
(American Geophysical Union, 2010-01)
The Madden-Julian Oscillation (MJO) is the dominant mode of atmospheric variability in the tropical atmosphere on intraseasonal time scales (i.e., weeks to seasons). This study examines the connection between the MJO and ...
A modified galerkin-spectral model for three-dimensional, barotropic, wind-driven shelf circulation
(1993)
The authors describe an efficient numerical scheme for calculating wind-driven currents on the continental shelf. Our scheme is based on the spectral approach introduced by Heaps and subsequently modified by Lardner. The ...
Surface heat flux, horizontal advection, and the seasonal evolution of water temperature on the Scotian Shelf
(1994)
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 ...
Predicting mesoscale variability of the North Atlantic using a physically motivated scheme for assimilating altimeter and Argo observations
(American Meteorological Society, 2009-07)
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 ...
Mapping the relationship between northern hemisphere winter surface air temperature and the Madden-Julian oscillation
(American Meteorological Society, 2011-08)
A regression-based modeling approach is described for mapping the dependence of atmospheric state variables such as surface air temperature (SAT) on the Madden-Julian oscillation (MJO). For the special case of a linear ...
Sea level and circulation variability of the Gulf of Carpentaria; influence of the Madden-Julian Oscillation and the adjacent deep ocean
(American Geophysical Union, Washington, DC, 2011)
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 ...
