AbstractBased on the particles dynamics in the radiation belts and the principles of their movement, we establish the particles trajectory simulation method in the radiation belts. On this basis, we first use data of particles in the inner zone for nearly two solar cycles provided by the low altitude weather satellites TIROS/NOAA, and then analyze the change of the flux of high-energy protons in various time and energy scales, as well as the relationship between electron flux angle and electron flux changes in order to obtain the dynamic evolution of computer radiation belt particles numerical simulation. It can be seen from the simulation results that the flux of protons have increased significantly and varied along with both the eleven-year solar cycle and seasons. Besides, the larger the particle energy, the greater the drift velocity, the results and the theoretical predictions are consistent.; Based on the particles dynamics in the radiation belts and the principles of their movement, we establish the particles trajectory simulation method in the radiation belts.
