The Effects of Magnetic Storm Phases on F-Layer Irregularities from Auroral to Equatorial Latitudes
Abstract
In progress is a major study of the effect of the ring current on the sub-auroral and equatorial generation of patches of irregularities. In addition studies are on-going for determining the dynamics of electric field penetration in latitude with the start of a major geomagnetic storm. For the first time simultaneous observations of irregularities at high and equatorial latitudes will be utilized. The studies use scintillation and spread F data as well as optical observations for data from 1971-1989. Two basic concepts are being studied. With the statistics of morphology of F-layer irregularities now in hand, it is possible to forecast in broad terms what to expect at equatorial, auroral and polar latitudes during various levels of solar flux. With the beginning of an understanding of the effect of the various phases of magnetic storms on generating irregularities as noted from the solar wind, ring current, convection, auroral index, and magnetic index parameters, it is possible to roughly forecast levels of F-layer irregularity intensity. With these in hand, the utility of space, time, and frequency diversity can be evaluated. Diversity could be used if forecasting in real time was possible.
