On the Stability of the California Undercurrent off Vancouver Island
Publisher: American Meteorological Society
Abstract: Recent satellite infrared imagery and hydrographic maps of the sea surface temperature of the northeast Pacific reveal a fairly regular pattern of cells or eddies that are aligned north-south about 150 km west of Vancouver ...
Equatorial Shelf Waves on an Exponential Shelf Profile
Publisher: American Meteorological Society
Abstract: The theory of barotropic nondivergent waves trapped on an exponential shelf lying on an equatorial ?-plane is presented. The bottom contours are parallel to the equator so that phase propagation is either eastward or ...
Generation of Annual Rossby Waves in the North Pacific
Publisher: American Meteorological Society
Abstract: A new mechanism is proposed for the generation of the annual-period baroclinic Rossby waves which have been observed in the central North Pacific by Kang and Magaard. It is shown that annual north-south fluctuations in the ...
A Latent-and Sensible-Heat Polynya Model for the North Water, Northern Baffin Bay
Publisher: American Meteorological Society
Abstract: The Pease latent-heat polynya model is coupled to a reduced-gravity, coastal upwelling model in order to simulate the formation and maintenance of the North Water (NOW), the Arctic's largest polynya, located in northern ...
A Teleconnection Study of Interannual Sea Surface Temperature Fluctuations in the Northern North Atlantic and Precipitation and Runoff over Western Siberia
Publisher: American Meteorological Society
Abstract: The spatial distributions of northern North Atlantic sea surface temperature and the high-latitude Northern Hemisphere sea level pressure anomalies averaged over six consecutive warm SST winters (1951?1956) and six consecutive ...
A Simple Coupled Atmosphere–Ocean–Sea Ice–Land Surface Model for Climate and Paleoclimate Studies
Publisher: American Meteorological Society
Abstract: The authors develop a coupled atmosphere?ocean?sea ice?land surface model for long-term climate change studies that incorporates the seasonal cycle. Three ocean basins, the Antarctic Circumpolar Current region, and the ...
Rossby Wave Driven Eulerian Mean Flows Along Non-Zonal Barriers, with Application to the Hawaiian Ridge
Publisher: American Meteorological Society
Abstract: We show that the reflection of baroclinic Rossby waves from a non-zonal barrier generates a Eulerian mean flow along the barrier. In order to produce a mean current of realistic magnitude, friction (in the form of Rayleigh ...
Trapped Coastal Waves on an Equatorial Beta Plane
Publisher: American Meteorological Society
Abstract: This paper describes the zonally propagating wave modes of a homogeneous fluid on an equatorial beta-plane with linear bottom topography. The fluid is bounded above by a free surface and bounded below by a depth profile ...
Dynamical Interpretation of Satellite-Sensed Thermal Features off Vancouver Island
Publisher: American Meteorological Society
Abstract: Two series of very high resolution thermal infrared satellite images, off Vancouver Island, are examined for evidence of baroclinic waves. A 1979 winter sequence of three images exhibits cold tongues, extending seaward ...
Resonant Interactions between Shelf Waves, with Applications to the Oregon Shelf
Publisher: American Meteorological Society
Abstract: From the inviscid, unforced, barotropic long-wave equations for a rotating system, it is shown that resonant interactions between three continental shelf waves can occur. Evolution equations governing the amplitude and the ...
