Modeling F region gravity waves observed during the WAGS campaign. I. Special event. II. Background wave spectra. [Worldwide Atmospheric Gravity wave Studies on traveling ionospheric disturbances]
Two types of disturbances observed in the ionization density and the line-of-sight ion velocity data from the Worldwide Atmospheric Gravity Wave Study are analyzed and compared with theoretical studies. The study concentrates on the source-response relationship between auroral activities and gravity waves observed in the F-region. In the first section, the measured and derived wave parameters for a semiperiodic TID observed on October 18, 1985 during a moderately magnetically active period are shown to be consistent with predictions from wave theory. In the second section, the background wave spectra observed during several magnetically quiet days are analyzed. It is shown that the neutral vertical velocity spectrum can be modeled as a power law type spectrum. The overall kinetic energy of this spectrum is calculated and compared with the TID. 32 references.
