WebA field-aligned irregularity ( FAI) is an anisotropic (different values when measured in different directions) perturbation of plasma density associated with magnetic fields. FAIs are often thought of in the context of the Earth's ionosphere where several natural processes generate FAIs in the E-region and F-region.
