Title: Excitation of mixed Rossby-gravity waves by wave-mean flow interactions on the sphere.

The equatorial mixed Rossby-gravity wave (MRGW) is an important contributor
to tropical variability. Its excitation mechanism capable of explaining the
observed MRGW variance peak at synoptic scales remains elusive. This study
investigates wave-mean flow interactions as a [...]
