Abstract: We propose to detect the interference effect between the atmospheric-scale and solar-scale waves of neutrino oscillation, one of the key consequences of the three-generation structure of leptons. In vacuum, we show that there is a natural and general way of decomposing the oscillation amplitude into these two oscillation modes. The nature of the interference is cleanest in the ${\overline{\ensuremath{\nu}}}_{e}$ disappearance channel, since it is free from the $CP$ phase $\ensuremath{\delta}$. We find that the upcoming JUNO experiment offers an ideal setting to observe this interference with more than $4\ensuremath{\sigma}$ significance, even under conservative assumptions about the systematic uncertainties. Finally, we discuss the relationship between the mass-ordering resolution and the interference effect.
