When waves generated by either the two-stream or the gradient drift instability in the equatorial electrojet have a finite but small wave vector component k∥ parallel to the magnetic field, they propagate completely differently from the k∥=0 case. (However, they still can be amplified.) Their group velocity is directed within 1¿ or 2¿ of the magnetic field. In addition, the perpendicular component of their group velocity, which is much smaller than the parallel component, can nonetheless be an order of magnitude larger than it is in the k∥=0 case heretofore treated. In this paper the two-dimensional propagation (in the meridian plane) of these waves is investigated qualitatively, and its principal features are shown to depend solely on general properties of the equilibrium electrojet configuration, for which we present a simple analytical model. Waves bounce back and forth along field lines between reflection points symmetrically placed north and south of the geomangetic equator. At the same time they convect vertically. In contras to the k∥≠0 waves has a chnage of sign at a certain altitude. Thus some waves propagate, while bouncing in the north-south direction, to the top of the electrojet and some to the bottom. We speculate on the possibly significant changes that inclusion of parallel propagation might bring to calculations of linear convective amplification and nonlinear saturation theories of type 1 irregularities.
