Characteristics of LF Whistler-Mode Waves Observed in Conjugate Area at Low Latitudes

  • Y. Tanaka
  • M. Nishino


Based on measurements of whistler-mode waves of Decca navigation signals in the magnetic conjugate area of the transmitters around Birdsville (L=l.55), Australia, characteristics of LF whistler-mode waves are indicated. The shift of transmitter frequency and the signal intensity increase are discussed mainly in relation to geomagnetic activities. Storm-related energetic electrons and magnetospheric electric fields penetrating into the low-latitude magneto- sphere may generate the intensity increase and the frequency shift. Also, the ducted propagation of LF whistler-mode signals is clarified.
