Post World War II Trends in Tropical Pacific Surface Trades
Publisher: American Meteorological Society
Abstract: Multidecadel time series of surface winds from central tropical Pacific islands are used to compute trends in the trade winds between the end of WWII and 1985. Over this period, averaged over the whole region, there is no ...
On the Diffusion Parameterization of Mesoscale Eddy Effects from a Numerical Ocean Experiment
Publisher: American Meteorological Society
Abstract: A method for evaluating the utility of a given parameterization field in a spatially inhomogeneous circulation is described. This method is used to examine the mean field diffusion parameterization of the heat, momentum ...
Some Eulerian-Scale Analysis Results: Eddy Terms in the Mean Heat, Momentum and Vorticity Equations
Publisher: American Meteorological Society
Abstract: The question of the importance of mesoscale motions in the long time averaged ocean circulation is examined from the viewpoint offered by Eulerian scale estimates of the magnitudes of the explicit eddy and largest inviscid ...
Dissipation Mechanisms and the Importance of Eddies in Model Ocean Energy Budgets
Publisher: American Meteorological Society
Abstract: The importance of mesoscale eddies in the basin energy budgets of closed-basin numerical model oceanic systems that attempt to resolve such motions varies greatly from calculation to calculation. In existing calculations, ...
Eddy Lateral Vorticity Transport and the Equilibrium of the North Atlantic Subtropical Gyre
Publisher: American Meteorological Society
Abstract: Oceanic gyres defined by the mean zero wind-stress curl lines have been the focus of wind-driven ocean circulation theory since its beginnings. In the face of single-signed vorticity input from the curl of the wind stress ...
Monthly Mean Island Surface Winds in the Central Tropical Pacific and El Niño Events
Publisher: American Meteorological Society
Abstract: The monthly mean surface wind changes during recent ENSO events, as observed from 11 islands in the tropical Pacific, are described. Two different composite ENSO wind fields are evaluated and compared. The month-to-month ...
Loca1 and Remote Forcing of ENSO Ocean Waveguide Response
Publisher: American Meteorological Society
Abstract: Several experiments using an ocean general circulation model have been carried out in order to explore the degree to which the oceanic waveguide response during the 1982?83 ENSO event was 1ocally and remotely forced. ...
On Climatological Monthly Mean Wind Stress and Wind Stress Curl Fields over the World Ocean
Publisher: American Meteorological Society
Abstract: Using a version of the global surface marine observation historical data set, a new 1° spatial resolution global ocean surface wind stress climatology has been evaluated using the Large and Pond surface drag coefficient ...
Equatorial Sea Surface Temperature Sensitivity to Net Surface Heat Flux: Some Ocean Circulation Model Results
Publisher: American Meteorological Society
Abstract: Several primitive-equation ocean general circulation model experiments have been carried out in order to explore the sensitivity of equatorial sea surface temperature (SST) results to uncertainty in the net surface heal ...
Is the Upper Ocean Warming? Comparisons of 50-Year Trends from Different Analyses
Publisher: American Meteorological Society
Abstract: There is great interest in World Ocean temperature trends, yet the historical global ocean database has very uneven coverage in space and time. Previous work on 50-yr upper ocean temperature trends from the NOAA ocean data ...
