Horizontal Flow Map

Horizontal Flow Map

This result is a comparison between the absolute value of magnetic field (background in color) and the simulated velocity inferred from Time-Distance helioseismology. The arrows signify horizontal (convective) motion at the surface of the Sun. The longest arrow represent 1 km/sec velocity.
