Short summary
Acoustic-type waves are widespread in solar and space plasmas where they contribute to energy transport and release. We discovered a new channel for nonlinear coupling among oblique sound waves with vastly different wavelengths across the background magnetic field. The resulting nonlocal spectral transfer is much faster than the previously known transfer produced by the local interactions among waves with similar wavelengths.
