Topographically Controlled Flow Around a Deep Trough Transecting the Shelf off Kodiak Island, Alaska
Publisher: American Meteorological Society
Abstract: Current measurements core the axis of a deep trough normal to the coast and from the adjacent shelf show that the mean flow is barotropic and follows depth contours, conserving potential vorticity, to form a cyclonic vortex ...
An Alternate Method for Estimating Dynamic Height from XBT Profiles Using Empirical Vertical Modes
Publisher: American Meteorological Society
Abstract: A technique is presented that applies modal decomposition to estimate dynamic height (0?450 db) from XBT temperature profiles. STD data are used to establish empirical relationships between vertically integrated temperature ...
Interdecadal Variations in the Alaska Gyre
Publisher: American Meteorological Society
Abstract: Climatic dynamic topography variations in the Alaska gyre during the period 1968?1990 are described with an objective analysis of more than 12000 STD and XBT stations, and COADS wind stress data. Interannual dynamic height ...
Low-Frequency Pycnocline Depth Variability at Ocean Weather Station P in the Northeast Pacific
Publisher: American Meteorological Society
Abstract: Low-frequency variability of the depth of the main pycnocline at Ocean Weather Station P and over the northeast Pacific is examined in terms of the one-dimensional response to local Ekman pumping according to the Hasselmann ...
Diagnostic Model and Analysis of the Surface Currents in the Tropical Pacific Ocean
Publisher: American Meteorological Society
Abstract: A diagnostic model of the tropical circulation over the 0?30-m layer is derived by using quasi-linear and steady physics. The horizontal velocity is directly estimated from sea surface height (TOPEX/Poseidon), surface ...
Low-Frequency Variations in Currents near the Shelf Break: Northeast Gulf of Alaska
Publisher: American Meteorological Society
Abstract: We present current observations from depths of 20, 50, 100 and 175 m obtained over a 3-year period near the northeast Gulf of Alaska shelf break, and emphasize a 2-year continuous segment from 50 m depth. These records ...
Spatial Optimal Interpolation of Aquarius Sea Surface Salinity: Algorithms and Implementation in the North Atlantic
Publisher: American Meteorological Society
Abstract: method is presented for mapping sea surface salinity (SSS) from Aquarius level-2 along-track data in order to improve the utility of the SSS fields at short length [O(150 km)] and time [O(1 week)] scales. The method is ...
Satellite-Derived Surface Current Divergence in Relation to Tropical Atlantic SST and Wind
Publisher: American Meteorological Society
Abstract: The relationships between tropical Atlantic Ocean surface currents and horizontal (mass) divergence, sea surface temperature (SST), and winds on monthly-to-annual time scales are described for the time period from 1993 ...
Pacific Warm Pool Temperature Regulation during TOGA COARE: Upper Ocean Feedback
Publisher: American Meteorological Society
Abstract: The Hasselmann feedback model was applied to hindcast western Pacific warm pool sea surface temperatures (SST) with heat flux observations obtained near 2°S, 156°E from October 1992 to February 1993 during the Tropical ...
Validation and Error Analysis of OSCAR Sea Surface Currents
Publisher: American Meteorological Society
Abstract: Comparisons of OSCAR satellite-derived sea surface currents with in situ data from moored current meters, drifters, and shipboard current profilers indicate that OSCAR presently provides accurate time means of zonal and ...
