Observations and analysis of the unstable auroral E region during local afternoon to early morning hours, and modified two-stream waves as well as two kinds of waves associated with the turbulence created by such waves are identified. One of these types exhibits properties similar to those of type II waves reported in the literature, whereas the second type has a broader spectrum, is detected in all directions, and appears to be new. The onset of turbulence corresponds to an electric field threshold of the order of 20 m/Vm. The presence of an azimuthal asymmetry in both the threshold field and the observed phase velocities with systematically greater values is detected; they are attributed to the presence of a 50-m/s E-W neutral wind at E region heights. The maximum observed volume reflectivity for type I wave ranges exceeded 10 exp -11, and that of the secondaries was of the order of 20 dB smaller.
