Simulations of the Farley-Buneman Instability
For more information see the paper, Simulations of the Saturated
Farley-Buneman Instability in the Ionosphere, published in Geophysical
Research Letters by Meers Oppenheim, Niels Otani, and Corrado Ronchi.

a simulation of the Farley-Buneman two-stream instability.
The fundamental wave travels rightward while nonlinear
waves travel upward on the crests and downward in the valleys.
Higher Electron Drift Velocity

the same simulation where the electron drift speed is forced 50%
Linearized Electron Behavior

the same simulation where the electron behavior is linearized.
Lower Electron Drift Velocity - More Realistic Case for Equator
Click here to see a movie (484 Kb) of
a lower resolution simulation where the driving electric field, E0,
has been dropped to 15mv. This simulation is 4m long and 8m high.
