Impulse waves generated by snow avalanches: Momentum and energy transfer to a water body

Angular momentum transfer to a star by gravitational waves

and Introduction Interaction of a stochastic background of gravitational radiation with celestial systems changes their dynamical elements in a random manner and give rise to secular changes in time(Berttoti 1973, Mashhoon etal 1981, Khosroshahi and Sobouti 1997). It has been speculated that a study of such secular changes might serve as a possible mean of detecting gravitational radiation. In ...

Water waves generated by a moving bottom

Tsunamis are often generated by a moving sea bottom. This paper deals with the case where the tsunami source is an earthquake. The linearized water-wave equations are solved analytically for various sea bottom motions. Numerical results based on the analytical solutions are shown for the free-surface profiles, the horizontal and vertical velocities as well as the bottom pressure.

Parametrization of momentum and energy depositions from gravity waves generated by tropospheric hydrodynamic sources

The mechanism of generation of internal gravity waves (IGW) by mesoscale turbulence in the troposphere is considered. The equations that describe the generation of waves by hydrodynamic sources of momentum, heat and mass are derived. Calculations of amplitudes, wave energy ̄uxes, turbulent viscosities, and accelerations of the mean ̄ow caused by IGWs generated in the troposphere are made. A com...

Mechanics of snow avalanches

The main problems of mechanics of snow avalanches are those of: (1) predicting avalanches, (2) avalanche motion, (3) the action of an avalanche upon obstacles, (4) the air wave, (5) the slow moving snow cover and its interaction with protective constructions and (6) the problem of artificial release of avalanches. This paper surveys the modern state of scientific knowledge about the nature of p...
