Hayashi, Y., 1971: Large-scale equatorial waves destabilized by convective heating in the presence of surface friction. Journal of the Meteorological Society of Japan, 49(6),  458-466.

Abstract: The effect of surface friction is incorporated into a previous model (Hayashi, 1970) of large-scale equatorial waves destabilized by convective heating.

It is found that the growth rate of Rossby type waves is enhanced and that the wave structure in the surface layer is significantly affected by the surface friction. However, the essential features of the previous model are not much altered.
