Quasi-linear modeling of gyroresonance between different MLT chorus and geostationary orbit electrons

摘要: The contributions of dayside and nightside gyroresonance chorus waves to electron radiation belt evolution at L = 6.6 are detailedly differentiated via fully solving the two-dimensional Fokker-Plank equation. numerical results show that different regions play significantly roles. can cause obvious loss energetic electrons lower pitch angles weak energization larger angles. yield significant angles, but cannot efficiently resonate with angle. Due difficulty in Fokker-Planck equation, cross diffusion terms often ignored previous work. Here effect is further analyzed. On dayside, ignoring overestimates phase space density by several orders magnitude consequently incorrectly regarded as an effective mechanism. nightside, (PSD) about one order These suggest affect on both which should be included future models.
