RISA Coupling Mechanism for Wind and Waves
Publisher: American Meteorological Society
Abstract: The authors present a simple model for the dynamics that couple the atmospheric boundary layer and wind-generated waves. The model is empirically motivated by parameterizations for the sea state-dependent drag coefficient ...
The Response of Ocean Waves to Turning Winds
Publisher: American Meteorological Society
Abstract: A model is developed for the response of waves to turning wind, which we denote as the fetch relaxation model. Comparison is presented with the standard ? relaxation model pioneered by Hasselmann et al. The fetch relaxation ...
Relating Friction Velocity to Spectral Wave Parameters
Publisher: American Meteorological Society
Abstract: Field experiments, in the years since the JONSWAP results, have established fetch- and duration-limited relations for wave parameters such as total energy E0, peak frequency fp, and the Phillips α coefficient. The Canadian ...
The Influence of Air–Sea Roughness, Sea Spray, and Storm Translation Speed on Waves in North Atlantic Storms
Publisher: American Meteorological Society
Abstract: A coupled atmosphere?wave?sea spray model system is used to evaluate the impact of sea spray and wave drag on storm-generated waves, their height variations, and directional wave spectra in relation to the storm location ...
The Impacts of Climate Change on Autumn North Atlantic Midlatitude Cyclones
Publisher: American Meteorological Society
Abstract: This study explores how midlatitude extratropical cyclone intensities, frequencies, and tracks can be modified under warming-induced conditions due to enhanced greenhouse gas (GHG) concentrations. Simulations were performed ...
Cross-Polarized Synthetic Aperture Radar: A New Potential Measurement Technique for Hurricanes
Publisher: American Meteorological Society
Abstract: t an empirical C-band Cross-Polarization Ocean (C-2PO) model for wind retrievals from synthetic aperture radar (SAR) data collected by the RADARSAT-2 satellite. The C-2PO model relates normalized radar cross section (NRCS) ...
A Two-Scale Approximation for Efficient Representation of Nonlinear Energy Transfers in a Wind Wave Spectrum. Part II: Application to Observed Wave Spectra
Publisher: American Meteorological Society
Abstract: In Part I of this series, a new method for estimating nonlinear transfer rates in wind waves, based on a two-scale approximation (TSA) to the full Boltzmann integral (FBI) for quadruplet wave?wave interactions, was presented, ...
A Two-Scale Approximation for Efficient Representation of Nonlinear Energy Transfers in a Wind Wave Spectrum. Part I: Theoretical Development
Publisher: American Meteorological Society
Abstract: A new method for estimating the transfer rates in wind wave spectra is derived and tested, based on a two-scale approximation (TSA) to the total integral for quadruplet wave?wave interactions. Comparisons of this new ...
Remote Sensing of Ocean Waves by Polarimetric SAR
Publisher: American Meteorological Society
Abstract: A new method to measure ocean wave slope spectra using fully polarimetric synthetic aperture radar (POLSAR) data was developed without the need for a complex hydrodynamic modulation transform function. There is no explicit ...
