The rotation of the Earth leads to a change in the equation of motion because of the Coriolis force. We study how Earth’s rotation affects elastic wave propagation. We show that the Coriolis force does not deflect seismic rays because the medium that carries the waves moves with Earth’s rotation. However, Earth’s rotation causes a weak traverse component of P-waves and a weak longitudinal compo...
The work is devoted to a numerical analysis of the MCC-type equations describing strongly nonlinear waves in a two-layer fluid. Its novelties are in adding earth rotation (Coriolis force) and an oscillating forcing imitating a tidal current over a bottom feature. Tidal forcing is represented by an oscillating bottom hill which in most cases gives a reasonable approximation for the case of a fix...
Recently, it has been shown that under certain conditions, the Eyring-Powell fluid model can exhibit shearthickening properties without losing known Newtonian or shear-thinning properties. The and Modified fluids have great potential in enhancing armour production reducing cost of maintenance for bullet proof vests. Coriolis force, on other hand, explains natural phenomena such as direction cyc...
The Influence of Convective Thermal Forcing on the Three-dimensional Circulation around Squall Lines
The present study suggests that the three-dimensional circulation in the trailing stratiform region behind squall lines is primarily determined by the time-mean pattern of heating and cooling in the leading convective line. Analysis of the line-normal circulations show that they develop as thermally generated gravity waves spread away from the leading line. Midlevel line-end vortices are the re...
The motion of an incompressible fluid confined to a shallow basin with a slightly varying bottom topography is considered. Coriolis force, surface wind and pressure stresses, together with bottom and lateral friction stresses are taken into account. We introduce appropriate scalings into a three-dimensional anisotropic eddy viscosity model; after averaging on the vertical direction and consider...
Wind is the main external force that governs spreading of river plumes in sea. Many previous studies demonstrated direction (especially small plumes) generally coincides with wind direction. At same time, majority are strongly affected by Coriolis force, which also among baseline knowledge about plumes. In this study, we focus on deflection from induced received little attention before. For pur...
