For linear systems, the biorthogonal modes converge to the linear eigenmodes of the system in the limit of large ''N''. <ref>G. Kerschen and J. C.

The biorthogonal decomposition is also highly sensitive to globally correlated oscillations.
Recently, this property has been exploited to detect Zonal Flows.
