Wave Phenomena

As shown within the limits of gyrokinetics, drift-compression waves can propagate in the magnetosphere in the direction of energetic electron drift. Plasma is assumed to be composed of cold particles with hot additives such as protons with Maxwell distribution and electrons with inverse distribution. We have determined conditions of existence of such waves and their intensification due to resonance interaction with energetic electrons (drift instability). The results can be helpful for interpretation of observation of wave phenomena in the magnetosphere with frequencies in the range of geomagnetic pulsations Pc5 and below.

Transverse Resonance

Discrete very-low-frequency chorus emissions observed during the daytime at ground station Gulmarg (geomag. lat. 24°10′N) are reported. The generation of these emissions is explained in terms of transverse resonance interaction between whistler waves and counter-streaming energetic electrons. The theory is tested by evaluating different parameters.
