Observations of Surface Velocity Fields

1987
This brief review discusses several recent papers on the motions of individual sunspots and sunspot groups. Measurements of spot areas and positions from Mount Wilson white-light, full-disk plates were carried out for an interval covering most of this century. Rotation and meridional motions were derived from these measures.

Surface velocity radar stream gauging

2012
La technique de mesure des vitesses de surface par radar mobile séduit les équipes d'hydrométrie du fait de sa rapidité et de la simplicité de sa mise en ½uvre pour des jaugeages en crue. Les radars mobiles viennent ainsi compléter la flotte d'instruments déjà disponible dans les équipes.

Near-surface velocity reconstruction using surface wave inversion

2013
This thesis examines the feasibility of inverting surface waves in common shot point (CSP) scismic data for S- and P-wave velocities. Several approaches to surface wave inversion are examined: 1) separate Love and Rayleigh wave inversions for S- and P-wave velocities; 2) Love wave inversion for S-wave velocities that is then followed by Rayleigh wave ...

The phase velocity, ray velocity, and group velocity surfaces for a magneto-ionic medium

Journal of Plasma Physics, 1977
The phase velocity surface for waves propagating in a uniform cold plasma is sometimes misinterpreted as having the shape of a wave-front. A summary is presented of the correct interpretations of the phase velocity, ray velocity, and group velocity surfaces. A full set of computer generated plots of such surfaces are presented. These are intended as an
