Power spectral and polarization characteristics of Pi 2 pulsations at high latitudes
Latitudinal power spectra and polarization characteristics of Pi 2 pulsations in the vicinity of the auroral oval are investigated. It is confirmed that the polarization characteristics are dependent on the position of the auroral breakup and the westward traveling surge (WTS). Particularly, an emph...

Summary: | Latitudinal power spectra and polarization characteristics of Pi 2 pulsations in the vicinity of the auroral oval are investigated. It is confirmed that the polarization characteristics are dependent on the position of the auroral breakup and the westward traveling surge (WTS). Particularly, an emphasis is placed on the two latitudinal reversals in the sense of polarization i. e., the ellipticity changes negative in the center region of WTS. The amplitude distribution of Pi 2 pulsations in latitude indicates that the maximum amplitude is located in the equatorward portion of the westward electrojet. |
