Short summary
The unresolved paradox about the merging of two anticyclonic mesoscale eddies is studied. While the conservation laws of mass and total circulation were satisfied, the conservation of AM required inclusion of the orbital AM. Both the conservation of circulation and the orbital AM were overlooked in previous theoretical studies. The eddy kinetic energy decreased due to fusion, but the eddy potential energy increased. This behaves like a large-scale energy pump in inverse energy cascades.
