Momentum transfer and foam production via breaking waves in hurricane conditions
Ephim Golbraikh, Yuri M. Shtemler
Generated under hurricane conditions, a slip layer composed of foam, bubble emulsion, and spray determines the behavior of the surface drag with wind speed. This study enables us t…
On the escape of low-frequency waves from magnetospheres of neutron stars
Ephim Golbraikh, Yuri Lyubarsky
We study the nonlinear decay of the fast magnetosonic into the Alfvén waves in relativistic force-free magnetohydrodynamics. The work has been motivated by models of pulsar radio e…
Modeling of the drag and thermal conductivity coefficients in tropical cyclones taking into account foam cover
Ephim Golbraikh, Yuri M. Stemler
A formal averaging procedure over the air-sea interface is developed for both momentum and enthalpy surface-transfer coefficients, C_D and C_K, in hurricane conditions. This leads…
Correlation between Foam-Bubble Size and Drag Coefficient in Hurricane Conditions
Ephim Golbraikh, Yuri M. Shtemler
Recently proposed model of foam impact on the air sea drag coefficient Cd has been employed for the estimation of the efficient foam-bubble radius Rb variation with wind speed U10…
Hindered energy cascade in highly helical isotropic turbulence
Rodion Stepanov, Ephim Golbraikh, Peter Frick +1
The conventional approach to the turbulent energy cascade, based on Richardson-Kolmogorov phenomenology, ignores the topology of emerging vortices, which is related to the helicity…
Drag coefficient for the air-sea exchange: foam impact in hurricane conditions
Ephim Golbraikh, Yuri M. Shtemler
A physical model is proposed for the estimation of the foam impact on the variation of the effective drag coefficient, C_d, with reference to the wind speed U10 in stormy and hurri…
