Sentence examples for chorus generated from inspiring English sources
While we focused on the spectral properties of chorus generated under the realistic initial condition of the background magnetic field, the dynamics of resonant electrons under the realistic conditions should be investigated in detail and is left as our future study.
H index could be then calculated for each of the 300 chorus generated (Fig. S1 and Tables S1, S2).
On the dayside, however, the flux of suprathermal electrons is much lower and chorus generated near the equator in the lower band propagates to higher latitudes and lower relative frequencies where it may be observed as low-frequency chorus.
Chorus are generated at the magnetic equator, where the intensity of the background magnetic field becomes minimum along a field line, and propagate away from the equator with increasing their wave amplitude.
The typical frequency range of whistler-mode chorus waves generated in the equatorial region is 0.1–(0.8f_{mathrm{ce}}) and correspond to a range from several hundred Hz to several dozen kHz in the inner magnetosphere, where (f_{mathrm{ce}}) denotes the local electron cyclotron frequency (Santolík et al. 2003b, 2004; Tsurutani and Smith 1974).
Since chorus elements generated in the region close to the magnetic equator intrinsically show sub-packet structures in the spectra, the results of the present study reveal that wave spectra measured by satellites in the region away from the equator should be formed by a combination of the intrinsic spectra and the spectral modulation by the propagationeffect.
Lower band chorus waves generated near the magnetic equator in the frequency range 0.1 fce–0.5 fallfall to lower relative frequencies as they propagate to higher latitudes and hence may fall into the low-frequency chorus band as defined here.
Whistler-mode chorus waves are generated around the equator outside the plasmapause during geomagnetic disturbances (Tsurutani and Smith 1974).
In the simulation, whistler-mode chorus waves are generated through nonlinear cyclotron resonant interaction between background thermal noise and anisotropic energetic resonant electrons.
Once coherent rising chorus waves are generated ( t > 6, 000 Ω e0 - 1 ), the absolute value of Wint increases significantly above 2 σw.
Hikishima et al. (2010) revealed that microburst precipitation of energetic electrons should occur due to the pitch angle scattering by the generated chorus emissions with rising tones.
