Supergranulation: Self-organization In The Surface Shear
Bulletin of the American Astronomical Society
American Astronomical Society, SPD meeting #37
Durham, New Hampshire
25 - 30 June 2006
Supergranular motions in the solar photosphere are implicated in phemomena as diverse as the global solar dynamo and the heating of the solar chromosphere, yet the origin of these motions is only poorly understood. Moreover, recent observations have revealed several startling properties of the flows: a wavelike spectrum, longitudinal alignment of the pattern, and very weak thermal contrast. This talk will review our current understanding of the solar supergranulation, the possible origin of its scale, and a proposed connection between its newly discovered properties and the helioseismically observed surface shear layer.
