Nonlinear mechanism of tsunami wave generation by atmospheric disturbances
Nonlinear mechanism tsunami wave generation atmospheric disturbances
2009/12/9
The problem of tsunami wave generation by variable meteo-conditions is discussed. The simplified linear and nonlinear shallow water models are derived, and their analytical solutions for a basin of co...
The Estimation of Wind-Wave Generation in a Discrete Spectral Model
Wind-Wave Generation Discrete Spectral Model
2009/2/9
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 t...
Trench Wave Generation by Incident Baroclinic Rossby Waves
Trench Wave Incident Baroclinic Rossby Waves
2009/1/15
We consider the response of a two-layer fluid in a coastal trench to the incidence of low-frequency Rossby waves from the open ocean. While both barotropic and baroclinic incident waves have been inco...
An Experimental and Numerical Study of the Internal Wave Generation by Tide—Topography Interaction
Internal Wave Generation Tide—Topography Interaction
2008/12/27
A stratified fluid response to barotropic oscillatory now over a large-amplitude obstacle is examined on the basis of the results of laboratory and numerical experiments. It is demonstrated that, when...
Long-Wave Generation Due to the Refraction of Short-Wave Groups over a Shear Current
Long-Wave Generation Shear Current Short-Wave Groups
2008/12/27
The generation of long waves by short-wave groups propagating over a shear current is studied. The incident wave groups consist of two co-linear short waves with slightly different frequencies. These ...
Quasi-linear Theory of Wind-Wave Generation Applied to Wave Forecasting
Quasi-linear Theory Wind-Wave Generation Wave Forecasting
2008/12/24
The effect of wind-generated gravity waves on the airflow is discussed using quasi-linear theory of wind-wave generation. In this theory, both the effects of the waves and the effect of air turbulence...
A Simplified Quasi-Linear Model for Wave Generation and Air–Sea Momentum Flux
Wave Generation Quasi-Linear Model Air–Sea Momentum Flux
2008/12/19
A simplified model is described for wave generation and air–sea momentum flux. The model is based upon the quasilinear theory employed by Fabrikant and Janssen, in which the mean flow is approximated ...
On Janssen’s Model for Surface Wave Generation by a Gusty Wind
Janssen’s Model Surface Wave Generation Gusty Wind
2008/11/17
Janssen’s model for the effect of gustiness on the mean energy transfer from a turbulent wind to a surface wave is simplified through a Gauss–Hermite approximation to his probability integral. Two exa...
Tsunami wave generation by the eruption of underwater volcano
Tsunami wave generation eruption underwater volcano
2009/12/30
Eruption of volcanoes represents one of important origins of tsunami waves and is responsible for most catastrophic tsunami (Krakatau, 1883; Thira, BC). The products of volcano eruption include solids...
