Simulations of the Farley-Buneman Instability
Baseline Case
Click here to see a movie (325 Kb) of
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
Click here to see a movie (267 Kb) of
the same simulation where the electron drift speed is forced 50%
higher.
Linearized Electron Behavior
Click here to see a movie (542 Kb) of
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.

Farley-Buneman Instability in the Ionosphere, published in Geophysical
