VORTONS

An ellipsoid of potential vorticity, surrounded by a halo of dynamic pressure anomaly, distorts the isentropic surfaces above and below it.

QG JET STREAK

A dipole of potential vorticity in a uniform mean flow exhibits a confluent-diffluent pressure field and distorts the isentropic surfaces above and below it.
