The Naval Research Laboratory high latitude ionosphere-magnetosphere mesoscale coupling model has been generalized to include scale-size dependent magnetospheric coupling and E-region Hall and Pedersen conductivity effects. With this model, the nonlinear evolution of plasma interchange-like instabilities in the high latitude F-region ionosphere has been studied using computer simulation techniques. The power spectra of density and electric field irregularities have been computed from the simulations and are found to be in agreement with observations. Applications to density irregularities in and near convecting patches, blobs, and arcs in the high latitude ionosphere are discussed.
