Abstract:
It has been demonstrated that chorus whistler mode waves are fundamentally important in the acceleration of the relativistic particles within the outer radiation belt. And they are equally important factor in the loss mechanisms of the same particles. To properly model the radiation belts and these wave particle interactions it is necessary to define the distributions of the wave amplitudes and power. Some theories suggest the wave particle interaction processes are impulsive and therefore influenced more by the largest of wave field strengths, where as other models imply a more stochastic effect and thus dictated by consistent wave power. Likely both processes are in effect, and therefore understanding the distributions and occurrences of both the largest amplitudes and distributive wave mode power are important. Utilizing 3+ years of Van Allen Probes Magnetic and Electric field measurements from the EMFISIS instrument we investigate the occurrence and mode parameter statistics of the peak field strengths and the average wave mode power of the observed waves.
