A recently developed theory of 'almost 2D' turbulence (Albert et al., 1990) is applied to E x B fluctuations in the E region equatorial electrojet. This theory of plasma turbulence in an external magnetic field extends strictly 2D theory (e.g., Sudan and Keskinen, 1979) to include weak phase variations along the magnetic field. Based on the direct interaction approximation of Kraichnan (1959), it describes the tendency of spectral energy to transfer nonlinearly toward modes with high k-parallel despite strong linear damping of these modes. Here, application of this theory to the aspect angle k-parallel/k of fluctuations at 3-m scales, for which radar backscatter measurements have been made (Kudeki and Farley, 1989) is discussed. Allowing for uncertainty in characterizing the plasma turbulence, good agreement is found except at the lowest altitudes of the electrojet.
