Barotropic ambient potential vorticity and barotropic streamfunction. Contour lines denote barotropic ambient potential vorticity f/H (contour interval: 5 × 10−10 s−1 m−1) and shade denotes streamfunction derived from the JCOPE2 reanalysis. Closed contours of f/H are present over the rises A, A′, and C
