Singular tidal modes and the regularization of the tidal singularity

Abstract: We seek to examine the behaviour of the shear layer emitted at the critical latitude in 3D in a spherical shell fille with rotating fluid. The significant difference seems to be a logarithmic singularity on the rotation axis formed by a cone of shear converging to an apex. We seek then to regularise this singularity via the split-disc arrangement and finally consider free-shear layers in 3D with a large-scale forcing.
