Relationship of the characteristics of magnetohydrodynamic waves to plasma density gradients near L = 4.
Excitation and localization characteristics of MHD waves present in the earth's magnetosphere are analyzed, with special emphasis on the importance of magnetospheric plasma density gradients in determining wave localizations. A summary is presented of a study of the relationships of MHD wave characteristics to the latitude profiles of topside electron density profiles observed by the ISIS 2 satellite near the same local and universal times. The wave polarization/plasma gradient observations presented are discussed in the context of theoretical considerations of hydromagnetic wave excitation. Also discussed is the impulse excitation of ULF waves.
