Fig. 2: Divergence and vorticity fields.
From: Global mantle convection models produce transform offsets along divergent plate boundaries
Sequence of non-dimensional velocity field divergence snapshots (left column) and corresponding radial vorticity fields (right column). The fields shown are the regions inside the green boxes drawn on the global field snapshots presented in Supplementary Fig. 4. The negative vorticity in the example circled-location is caused by relative plate motion in the directions indicated by the white arrows.
