RISDecadal and Multidecadal North Atlantic SST Anomalies Driven by Standing and Propagating Basin-Scale Atmospheric Anomalies
Publisher: American Meteorological Society
Abstract: North Atlantic winter surface atmospheric circulation anomalies that vary over decadal and longer periods are characterized by examining the life history of individual anomaly features present from 1950 to 1992. Individual ...
Simulation of North Atlantic Decadal/Multidecadal Winter SST Anomalies Driven by Basin-Scale Atmospheric Circulation Anomalies
Publisher: American Meteorological Society
Abstract: The North Atlantic winter sea surface temperature anomaly (Tsa) response to anomalous surface atmospheric circulation anomalies that vary over decadal and short-term inter-decadal periods is simulated for 1950 through 1992. ...
Large-Scale SST Variability in the Western North Atlantic Subtropical Convergence Zone during FASINEX. Part II: Upper Ocean Heat Balance and Frontogenesis
Publisher: American Meteorological Society
Abstract: We analyzed the influence of wind-deriven horizontal heat advection on the large-scale [O(1000) km wavelength] variability of both the upper-ocean mixed-layer heat content and the subtropical frontal zone (SFZ) within an ...
Large-Scale SST Variability in the Western North Atlantic Subtropical Convergence Zone during FASINEX. Part I: Description of SST and Wind Stress Fields
Publisher: American Meteorological Society
Abstract: We describe properties of large-scale fluctuations in the wind field represented by two analyses (FNOC and NOAA ATOLL), and in the SST field represented by maps derived from 5-day composite AVHRR images, within an 11° ...
Frequency Response Properties of Forced Climatic SST Anomaly Variability in the North Atlantic
Publisher: American Meteorological Society
Abstract: Frequency response properties of North Atlantic (5°?57°N) sea surface temperature anomaly (Tsa) variability with periods of several months to 20 years are characterized using the Comprehensive Ocean-Atmosphere Data Set ...
Large-Scale Sea Level Response to Atmospheric Forcing along the West Coast of North America, Summer 1973
Publisher: American Meteorological Society
Abstract: Along the west Coast of North America, the response of sea level to fluctuations in alongshore wind stress at large alongshore scales (> 1000 km) accounted for a substantial faction of the total sea level variance during ...
Meanders of the Gulf Stream Downstream from Cape Hatteras 1975–1978
Publisher: American Meteorological Society
Abstract: Weekly Gulf Stream paths within 1000 km downstream of Cape Hatteras were obtained for 1975?78 from the Navy's weekly EOFA charts based on satellite IR imagery. They displayed two dominant meander modes: first, a standing ...
Westward-propagating SST Anomalies and Baroclinic Eddies in the Sargasso Sea
Publisher: American Meteorological Society
Abstract: Previous studies have documented the existence of a zonal band of strong, persistent, westward-propagating sea surface temperature (Ts) anomalies with zonal wavelengths of ≈800 km and periods of ≈200 days that are confined ...
Westward-propagating SST Anomaly Features in the Sargasso Sea, 1982–88
Publisher: American Meteorological Society
Abstract: Sea surface temperature (Ts) maps of the region from 59.5° to 75.5°W, 22.5° to 33.5°N containing the western North Atlantic Subtropical Convergence Zone (STCZ) were derived from AVHRR/2 images. The 7- year mean annual cycle ...
The Response of Quasigeostrophic Oceanic Vortices to Tropical Cyclone Forcing
Publisher: American Meteorological Society
Abstract: he response of quasigeostrophic (QG) oceanic vortices to tropical cyclone (TC) forcing is investigated using an isopycnic ocean model. Idealized oceanic currents and wind fields derived from observational data acquired ...
