This is the third in a series of papers that deal with angular momentumtransport by internal gravity waves. We concentrate on the waves excited bycore convection in a 3Msun, Pop I main sequence star. Here, we want to examinethe role of the Coriolis acceleration in the equations of motion that describethe behavior of waves and to evaluate its impact on angular momentum transport.We use the so-called traditional approximation of geophysics, which allowsvariable separation in radial and horizontal components. In the presence ofrotation, the horizontal structure is described by Hough functions instead ofspherical harmonics. The Coriolis acceleration has two main effects on waves.It transforms pure gravity waves into gravito-inertial waves that have a largeramplitude closer to the equator, and it introduces new waves whose restoringforce is mainly the conservation of vorticity. Taking the Coriolis accelerationinto account changes the subtle balance between prograde and retrograde wavesin non-rotating stars. It also introduces new types of waves that are eitherpurely prograde or retrograde. We show in this paper where the local depositionof angular momentum by such waves is important.
