Nonlinear Theory of the Collisional Rayleigh-Taylor Instability in Equatorial Spread F.
Abstract
The nonlinear behavior of the collisional Rayleigh-Taylor instability is studied in equatorial Spread F by including a dominant two-dimensional nonlinearity. It is found that on account of this nonlinearity, the instability saturates by generating damped higher spatial harmonics. This saturated power spectrum for the density fluctuations goes like 1/k squared. A comparison between experimental observations and theory is presented. (Author)
