N2 - In this paper, the main statements of the problem of a non-zonal vortex layer on the β-plane in the Miles - Ribner formulation are applied to observations in the real ocean. Earlier, we showed that when waves interact with a non-zonal flow, a new class of solutions appears, which is absent in the case of a zonal flow. This new class of solutions can be interpreted as pure radiation of Rossby waves by a nonzonal flow. The analysis of the space-time diagrams in the region under consideration confirms the previously obtained theoretical conclusions of the problem of the interaction of planetary waves with a non-zonal flow on the β-plane in the Miles - Ribner formulation. Incident, reflected and refracted waves are distinguished. It is shown that Rossby waves propagating from east to west at a speed of 7.6 cm/s are transformed into refracted and reflected waves when interacting with the current. The refracted waves propagate against the current, to the southwest, at a speed of 4.6 cm/s. The reflected waves propagate to the southeast, perpendicular to the current, at a speed of 7.8 cm/s. The speed of reflected waves exceeds the speed of incident waves, which confirms the conclusions about the existence of mechanisms for amplifying planetary waves when they interact with a non-zonal flow.
