Tracking granules on the Sun’s surface and reconstructing horizontal velocity fields: I. the CST algorithm
Aims. Determination of horizontal velocity fields on the solar surface is crucial for understanding the dynamics of structures like mesogranulation or supergranulation or simply the distribution of magnetic fields. Methods. We pursue here the development of a method called CST for coherent structure tracking, which determines the horizontal motion of granules in the field of view. Results. We f...
متن کاملTracking granules at the Sun ’ s surface and reconstructing velocity fields . II . Error analysis
Context. The determination of horizontal velocity fields at the solar surface is crucial to understanding the dynamics and magnetism of the convection zone of the sun. These measurements can be done by tracking granules. Aims. Tracking granules from ground-based observations, however, suffers from the Earth’s atmospheric turbulence, which induces image distortion. The focus of this paper is to ...
متن کاملASTRONOMY AND ASTROPHYSICS Are granules good tracers of solar surface velocity fields?
Using a numerical simulation of compressible convection with radiative transfer mimicking the solar photosphere, we compare the velocity field derived from granule motions to the actual velocity field of the plasma. We thus test the idea that granules may be used to trace large-scale velocity fields at the sun's surface. Our results show that this is indeed the case provided the scale separatio...
متن کاملReconstructing the Original Ejection Velocity Fields of Asteroid Families
The kinematical properties of the fragment ejection processes in the events that produced the presently known asteroid families have long been poorly known due to the presence of a couple of unknown angles (the true anomaly and the argument of the perihelion of the parent body at the epoch of the family formation) in Gauss' equations. In the present paper a general procedure for obtaining a rel...
متن کاملReconstructing Basin-Scale Eulerian Velocity Fields From Simulated Drifter Data
A single-layer, reduced-gravity, double-gyre primitive equation model in a 2000 km 3 2000 km square domain is used to test the accuracy and sensitivity of time-dependent Eulerian velocity fields reconstructed from numerically generated drifter trajectories and climatology. The goal is to determine how much Lagrangian data is needed to capture the Eulerian velocity field within a specified accur...
