The Estimation of Wind-Wave Generation in a Discrete Spectral Model
Publisher: American Meteorological Society
Abstract: The estimation of wind-wave generation using a new discrete spectral model is compared to Hasselmann et al.'s (1976) parametric model and to models driven primarily by direct transfer of energy from the atmosphere into the ...
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 ...
Inconsistent Spectral Evolution in Operational Wave Models due to Inaccurate Specification of Nonlinear Interactions
Publisher: American Meteorological Society
Abstract: The introduction of third-generation (3G) models was based on the premise that wave spectra could evolve without prior shape restrictions only if the representation for nonlinear interactions contained as many degrees of ...
Recent Secular Variations in Mid-Atlantic Winter Extratropical Storm Climate
Publisher: American Meteorological Society
Abstract: An increase in storm damage along the east coast of the United States coincides with secular variations of the general circulation documented by several recent investigations. To determine the coupling between large-scale ...
The Influence of Storm Size on Hurricane Surge
Publisher: American Meteorological Society
Abstract: Over the last quarter-century, hurricane surge has been assumed to be primarily a function of maximum storm wind speed, as might be estimated from the Saffir?Simpson hurricane scale. However, Hurricane Katrina demonstrated ...
The Role of Nonlinear Momentum Fluxes on the Evolution of Directional Wind-Wave Spectra
Publisher: American Meteorological Society
Abstract: t has long been known that nonlinear wave?wave interactions produce stationary solutions related to constant energy flux through the equilibrium range when a deep-water spectrum follows an f?4 form, as has been verified ...
Wind Speed Scaling in Fully Developed Seas
Publisher: American Meteorological Society
Abstract: Recent tests of all generations of numerical wave models indicate that extreme wave heights are significantly underpredicted by these models. This behavior is consistent with the finding by Ewing and Laing that fully ...
