Wind stress in the presence of swell under moderate to strong wind conditions

11.4 Wind Stress and Wind Wave Observations in the Presence of Swell

The questions of how wind and ocean waves interact and how this coupling should be parameterized to optimally derive the surface wind stress remain open and central to estimating air-sea coupling at the global and local scales. While much attention has been given to evaluating the effect of the wind-driven waves upon the surface wind stress and air-sea drag coefficient, less emphasis has been g...

ASCAT wind quality under high subcell wind variability conditions

The assessment and validation of the quality of satellite scatterometer vector winds is challenging under increased subcell wind variability conditions, since reference wind sources such as buoy winds or model output represent very different spatial scales from those resolved by scatterometers (i.e., increased representativeness error). In this paper, moored buoy wind time series are used to as...

Modification of the Charnock Wind Stress Formula to Include the Effects of Free Convection and Swell

Wind Turbine Performance Under Icing Conditions

Department of Aeronautical and Astronautical Engineering, University of Illinois at Urbana-Champaign, 306 Talbot Laboratory, 104 S. Wright Street Urbana. IL 61801-2935 The effects of rime ice on horizontal axis wind turbine performance were estimated. For typzcal supercooled fog conditions found in cold northern regions, four rime ice accretwns on the 5809 wmd turbine airfoil were predicted usi...

the effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
