Abstract: A system and method forecast geomagnetic events and resulting currents from ground and space weather data, including solar wind velocity data and interplanetary magnetic field data. The system has a processor including a first prediction generator for predicting a midnight equatorial boundary (MEB) value; a second prediction generator for predicting a polar cap potential (PCP) value from the ground and space weather data; an AL and AU prediction generator for predicting AL and AU values; a pseudo Kp value generator for generating a pseudo Kp related value; an electric field pattern generator for determining electric field patterns from the pseudo Kp value, the PCP value, and the ground and space weather data; a conductivity generator for determining conductivity values from the ground and space weather data and the pseudo Kp value; and an adaptive feedback generator for adaptively generating the geomagnetic parameters from the conductivity values, the electric field values, and the predicted AL and AU values.
