In a recent paper (Buzzi et al., 1990), we discussed some observational results which indicated the presence of two modes in the probability density distribution of the planetary-scale wave amplitude during Northern Hemisphere (NH) summer. This result has important implications for the theory of low-frequency variability in the mid-latitudes as discussed in our paper. A possible explanation of the bimodality is the existence of a resonance in mid-latitudes faciliated by the trapping of wave activity due to the structure of the zonally avaraged flow.DOI: 10.1034/j.1600-0870.1992.00008.x
