High-frequency radio propagation at high latitudes is strongly affected by auroral absorption, which is known to occur sporadically in events known as auroral substorms. A brief discussion of the morphology of substorms is presented, followed by an analysis of auroral absorption during 60 substorms. The statistical parameters necessary to specify a predictive model are derived empirically as a function of time after substorm onset. Also presented from other evidence are relationships to model the latitude dependence, substorm duration, frequency dependence, and the seasonal and solar cycle dependence. A brief discussion of structure size in auroral absorption events is included. Author
