RISWind Stress Measurements from the Open Ocean
Publisher: American Meteorological Society
Abstract: An automatic inertial dissipation system was used during three cruises of the RRS Discovery in the Southern Ocean to obtain a large dataset of open ocean wind stress estimates. The wind speed varied from near calm to 26 m ...
A Mixed Spectral Finite-Difference 3D Model of Neutral Planetary Boundary-Layer Flow over Topography
Publisher: American Meteorological Society
Abstract: A simple three-dimensional linear model of planetary boundary-layer flow is developed based on the Mixed Spectral Finite-Difference model of Beljaars et al. using the full second-order turbulence closure of Launder et al. ...
A Comparison of Sensible and Latent Heat Flux Estimates for the North Atlantic Ocean
Publisher: American Meteorological Society
Abstract: Previously published estimates of the surface turbulent fluxes over the North Atlantic Ocean have been compared by applying the calculation methods used by each author to a common dataset of ship observations. The major ...
The Dependence of Sea Surface Roughness on the Height and Steepness of the Waves
Publisher: American Meteorological Society
Abstract: It is proposed that the sea surface roughness zo can be predicted from the height and steepness of the waves, zo/Hs = A(Hs/Lp)B, where Hs and Lp are the significant wave height and peak wavelength for the combined sea and ...
Comments on “On the Effect of Ocean Waves on the Kinetic Energy Balance and Consequences for the Inertial Dissipation Technique”
Publisher: American Meteorological Society
On the Apparent “Imbalance” Term in the Turbulent Kinetic Energy Budget
Publisher: American Meteorological Society
Abstract: A synthetic dataset is used to show that apparent variations between different stability classes in the mean drag coefficient, CD10n, to wind speed relationship can be explained by random errors in determining the friction ...
A Model for the Correction of Surface Wind Data for Sheltering by Upwind Obstacles
Publisher: American Meteorological Society
Abstract: Wakes behind 2D fences and 3D obstacles are reviewed with special emphasis on reduced mean wind speeds and sheltering effects. Based partly on Perera's study of wakes behind 2D fences, and assuming a Gaussian spread for ...
Accuracy of Humidity Measurement on Ships: Consideration of Solar Radiation Effects
Publisher: American Meteorological Society
Abstract: The effect of heating due to solar radiation on measurements of humidity obtained from ships is examined. Variations in wet- and dry-bulb temperature measured on each side of a research ship are shown to correlate with ...
Toward Estimating Climatic Trends in SST. Part I: Methods of Measurement
Publisher: American Meteorological Society
Abstract: To assess climatic changes in sea surface temperature (SST), changes in the measurement method with time and the effect of these changes on the mean SST must be quantified. Observations from the International Comprehensive ...
Choice of a Beaufort Equivalent Scale
Publisher: American Meteorological Society
Abstract: Beaufort equivalent scales from the literature have been compared to find the scale that gives the most homogenous, internally consistent, combined anemometer and visual wind speed data from the Comprehensive Ocean?Atmosphere ...
