The Latitudinal Distribution of Solar Sound Speed
The solar sound-speed distribution is not spherically symmetric. The figure shows the relative deviation from the spherically-symmetric sound-speed profile. The results are reliable between depths of 0.5 and 0.95 Rsun. In the deeper layers of the convection zone, sound-speed can be directly related to temperature, and thus the figure shows that the equatorial and lower-latitude regions of the Sun are cooler than the higher latitudes.
