Solar Subsurface Weather

Solar Subsurface Weather

• First Solar Weather Maps'' showing changing
  wind patterns on a star
• From time-distance and ring-diagram analysis
• Analyze acoustic wave fields of mosaics of
  tracked localized regions (each 15º square)
• Measure anisotropic frequency splittings of local
  f and p modes in power spectra
• Invert splittings to deduce flows with depth
• Large transient wind streams visible
• Major active regions exhibit prominent inflows in
  upper 7 Mm, outflows below 11 Mm
• Clear interplay between SSW flows and magnetic
  fields. (Who pushes whom around?)
• Flow evolution streaming features strengthen and
  converge toward active regions
