RISLate-Winter Generation of Spiciness on Subducted Isopycnals
Publisher: American Meteorological Society
Abstract: The origins of density-compensating anomalies of temperature and salinity (spice) are investigated using a model forced with the most realistic surface products available over the 40 years 1958?97. In this hindcast, the ...
Observational Evidence of Winter Spice Injection
Publisher: American Meteorological Society
Abstract: Temperature and salinity (T?S) profiles from the global array of Argo floats support the existence of spice-formation regions in the subtropics of each ocean basin where large, destabilizing vertical salinity gradients ...
Validation of Vertical Mixing in an Equatorial Ocean Model Using Large Eddy Simulations and Observations
Publisher: American Meteorological Society
Abstract: A nonlocal K-profile parameterization (KPP) of the upper-ocean boundary layer is tested for the equatorial regions. First, the short-term performance of a one-dimensional model with KPP is found to compare favorably to ...
An Evaluation of the WOTAN Technique of Inferring Oceanic Winds from Underwater Ambient Sound
Publisher: American Meteorological Society
Abstract: The potential of the WOTAN technique to estimate oceanic winds from underwater ambient sound is thoroughly evaluated. Anemometer winds and sound spectrum levels at 11 frequencies in the range 3?25 kHz from the FASINEX ...
Surface Ocean Fluxes and Water-Mass Transformation Rates in the Coupled NCAR Climate System Model
Publisher: American Meteorological Society
Abstract: The global distributions of the air?sea fluxes of heat and freshwater and water mass transformation rates from a control integration of the coupled National Center for Atmospheric Research (NCAR) Climate System Model (CSM) ...
Approach to Equilibrium in Accelerated Global Oceanic Models
Publisher: American Meteorological Society
Abstract: The approach to equilibrium of a coarse-resolution, seasonally forced, global oceanic general circulation model is investigated, considering the affects of a widely used acceleration technique that distorts the dynamics ...
Basin-Scale, High-Wavenumber Sea Surface Wind Fields from a Multiresolution Analysis of Scatterometer Data
Publisher: American Meteorological Society
Abstract: A numerical technique sensitive to both spectral and spatial aspects of sea surface wind measurements is introduced to transform the irregularly sampled satellite-based scatterometer data into regularly gridded wind fields. ...
The Mean Annual Cycle in Global Ocean Wind Stress
Publisher: American Meteorological Society
Abstract: The mean annual cycle in surface wind stress over the global oceans from surface wind analyses from the European Centre for Medium Range Weather Forecasts (ECMWF) for seven years (1980?86) is presented. The drag coefficient ...
The Effective Drag Coefficient for Evaluating Wind Stress over the Oceans
Publisher: American Meteorological Society
Abstract: Computations of the surface wind stress and pseudostress over the global oceans have been made using surface winds from the European Centre for Medium Range Weather Forecasts for 7 years. The drag coefficient is a function ...
Surface Wind Variability on Spatial Scales from 1 to 1000 km Observed during TOGA COARE
Publisher: American Meteorological Society
Abstract: Near-surface wind spectra are considered from three very different data sources, covering a range of spatial scales from 100 to 103 km. The data were observed during the Tropical Ocean Global Atmosphere Coupled Ocean?Atmosphere ...
