Outline of Final Research Achievements |
We have newly developed simulation codes to investigate global variations of energetic electrons of the outer belt considering wave-particle interactions. As a result, we found that the whistler chorus waves can cause wide energy electron precipitations from a few keV to MeV simultaneously, which are confirmed by observations. Moreover, we found that the MHD mode waves can resonate with the drifting electrons and the prompt accelerations of MeV electrons are found associated with the solar wind pressure pulse.
