Geomagnetic and ionospheric variations are extremely important to the Navy because many C3 and surveillance systems depend upon the stability of the geomagnetic field and ionosphere for reliable operation. For example, rapid geomagnetic pulsations may obscure submarines from our ASW detectors, and ionospheric storm depletions or enhancements of the F-region may compromise covert Naval communications. To alleviate the damaging effects of these variations, a real-time environmental prediction/assessment system must be developed with inputs into a model describing effects of the variations on the system. This report documents the present understanding of both magnetospheric substorms and ionospheric storms, and suggests a program to expedite the development of an operational model for Naval use. Magnetospheric substorms appear to be the causative mechanism of the global ionospheric storm. A digest of the major models of magnetospheric substorms is presented in chapter 1. Chapter 2 discusses the ionospheric storms that are identified with magnetospheric substorms. (Author)
