title = "Effect of the subsurface shear layer on solar supergranulation",
abstract = "Supergranular convective cells on the Sun rotate faster than surface plasma or any other feature. Recent time-distance helioseismology results suggest that supergranulation also has properties of travelling waves. We suggest that these properties may be due to the steep gradient of the subsurface shear layer. We use a linear model to calculate phase speeds of the unstable convective modes. These phase speeds are greater than the speed of the surface plasma; however, they are significantly lower than the observed speed of the supergranular pattern. This suggests that the subsurface shear layer is a plausible explanation for the wave-like behaviour. An alternate suggested explanation is the effect of the Coriolis force. We analyzed the results of a model including solar rotation, and found no evidence of wave-like behaviour.",
