The atmospheric boundary layer over flat terrain has been                  extensively studied, and many of the results can be applied in a                local sense to less idealized conditions.  But undulating terrain               introduces unique effects which generate internal waves in the                  overlaying fluid, which will be reabsorbed at levels where the                  wind reverses.  Thus, the wind experiences wave-induced drag,                   turbulence, and horizontal eddying.  Current middle-atmosphere                  studies address such problems, and it should prove advantageous                 to both fields to address the boundary layer in a similar                       fashion.                                                                             This research also investigates a new type of atmospheric                  wave mode which requires a "lid" to prevent the wave energy from                leaking off into the upper atmosphere.  The lid for this new                    mode occurs at the height where its intrinsic frequency matches                 the local inertial frequency.  One consequence of this is that                  the duct properties change with latitude; in the tropical                       troposphere wave momentum can be funneled towards a destructive                 terminator in the subtropics.  Such wave-associated transports                  influence the distribution of zonal angular momentum.
