Abstract

We present details of large scale horizontal (mesogranular, supergranular) flows which have been discovered by measuring the motions of granules with local correlation techniques. Not only do the flows expel magnetic field from the centers of source regions to their boundaries, thus forming the well-known supergranular network, but they also exhibit convergence into sinks, and significant vorticity. The displacement, distortion, and twisting of magnetic field by such motions may lead to a better understanding of solar flare buildup processes, and an increased ability to predict the occurrence of flares.
