Abstract: A method of forecasting transport of a region of plasma density enhancement within a polar region is provided. The method comprises: providing a convection model for predicting electrostatic potential distribution within the polar region over time; determining the total electron content distribution within the polar region; and determining whether reconnection is occurring. If reconnection is determined to be occurring, the method comprises: identifying a region of plasma density enhancement using the total electron content distribution; and calculating a velocity of at least a portion of the plasma density enhancement using the convection model, such that transport of a region of plasma density enhancement over time can be forecast.
