Meridional flow in the Sun's convection zone is a single cell in each hemisphere (3 of 4)

Caption

Sound waves propagate throughout the Sun and can be measured at the solar surface, for example at A and B. Just as seismology is used to see inside the earth, helioseismology is used to see inside the Sun (here near the wave path connecting A and B). This material relates to a paper that appeared in the 26 June issue of Science, published by AAAS. The paper, by L. Gizon at Max-Planck-Institut für Sonnensystemforschung in Göttingen, Germany and colleagues was titled, "Meridional flow in the Sun's convection zone is a single cell in each hemisphere."
