Abstract

Recently Yoshimura has evaluated the gradient of the Sun's angular velocity (d$Omega$/dr) necessary to give a good fit to the observed solar activity cycle. We estimate the meridional velocities in the convection zone, implied by this value of d$omega$/dr. These meridional velocities are in good agreement with those necessary to explain the Sun's surface differential rotation.
