Abstract:

Developed novel multi-nesting, time splitting and implicit relaxation techniques for coupled three-dimensional mesoscalemicroscale ionospheric dynamics resolved secondary Rayleigh-Taylor instabilities and characterized turbulent dynamics of plasma bubblesionospheric layers. Created methods based on Lagrangian coherent structures delineating formation of scintillation producing irregularities, discovered fine scale irregularity patternsplasma pancakes in ionospheric flows described non-Gaussian spatially varying statistics and characterized patchy inhomogeneous dynamics of ionospheric density layers. Physics based predictive modeling and simulations of coupled neutral-plasma interactions ions, electrons and neutral winds enable forecasting of mesoscalemicro-scale dynamics for a range of altitudes that encompass the ionospheric E and F layers.
