Abstract
Large-scale F-region disturbances, which are manifested by changes in the global electron-density profile, are known to be accompanies by magnetic storms. The electron density in the F region is generally enhanced in low latitudes, while it is depressed in middle and high latitudes. Several mechanisms are considered to contribute to the electron-density change, and it is shown that the abundance ratio of atomic oxygen to molecular oxygen or nitrogen is a dominant parameter to control the electron-density change. A theoretical model of F-region storms, which is compatible with the observed features, is proposed.
