A Dynamic Roughness Equation and Its Application to Wind Stress Determination at the Air-Sea Interface
Publisher: American Meteorological Society
Abstract: A dynamic roughness equation including major wind and wave interaction parameters (wind shear velocity, wave height, and phase velocity) is derived. Because this equation implicitly incorporates the effects of wave steepness, ...
Determination of the Power-Law Wind Profile Exponent on a Tropical Coast
Publisher: American Meteorological Society
Abstract: Hourly measurements of temperature and wind speed (at 10 and 33 m) for a one-year period were made on the flat south coast of St. Croix, U.S. Virgin Islands. Values of the exponent p used in the power-law wind profile were ...
Correction of Land-Based Wind Data for Offshore Applications: A Further Evaluation
Publisher: American Meteorological Society
Abstract: A formula that linearly relates the difference in wind speed between onshore and offshore regions, as tested successfully in the Great Lakes region, has been revised and extended to other parts of the world. This formula ...
A Mechanism for the Increase of Wind Stress (Drag) Coefficient with Wind Speed over Water Surfaces: A Parametric Model
Publisher: American Meteorological Society
Abstract: A mechanism is proposed for a physical explanation of the increase in wind stress (drag) coefficient with wind speed over water surfaces. The formula explicitly incorporates the contribution of both winds and waves through ...

Effects of Surface Baroclinicity on Frontal Overrunning along the Central Gulf Coast
Publisher: American Meteorological Society
Abstract: Along the United States Gulf coast and over the northern Gulf of Mexico, frontal overrunning occurs frequently. Cyclogenesis over the Gulf is often associated with this type of weather system. Effects of baroclinic fields ...
Relationship between Monthly Frontal Overrunning and Offshore-Onshore Temperature Differences across the Central Gulf Coast
Publisher: American Meteorological Society
Abstract: Under geostrophic and hydrostatic conditions, the Margules equation for the equilibrium slope of a stationary front is applied to study the relationship between monthly frontal overrunning and the temperature difference ...
Estimating Overwater Convective Boundary Layer Height from Routine Meteorological Measurements for Diffusion Applications at Sea
Publisher: American Meteorological Society
Abstract: On the basis of hourly measurements of wind and air and sea surface temperatures for at least 6 yr at three buoy stations in the eastern Gulf of Mexico, the onset of the free convection regime, which coincides with the ...
A Relationship between the Bowen Ratio and Sea–Air Temperature Difference under Unstable Conditions at Sea
Publisher: American Meteorological Society
Abstract: At the air?sea interface, estimates of evaporation or latent heat flux and the Monin?Obukhov stability parameter require the measurements of dewpoint (Tdew) or wet-bulb temperature, which are not routinely available as ...
