Abstract:

An analytical model of a late time high altitude ionospheric striation is presented which incorporates characteristic shapes from recent simulations. The model striation is nonaxisymmetric with a long diffuse tail frontside, a compact core, and a steep backside. It contains six adjustable parameters to vary the shape and edge properties for sensitivity studies. Model parameters and the power spectral density PSD as observed from different view angles. Compare results of the model with Chesnuts PSD obtained from photographs of Checkmate. A good fit is obtained with our model without any size distribution of striations.
