    Abstract
  • Based on the proton flux distribution in the inner radiation belt obtained by FY-3A, it is found that the 3~5MeV energy channel shows a second anomalous region besides the South Atlantic Anomaly region. The anomaly zone is a sub-extreme area of proton flux, compared with the main South Atlantic Anomaly region, the new proton flux extremum is weaker and smaller, so it is called the sub South Atlantic Anomaly region. By selecting representative sample points in the main South Atlantic anomaly and sub South Atlantic anomaly areas, the formation mechanism of the sub South Atlantic Anomaly region is studied. The results show that the inner radiation belt proton flux approximately normally distributes with pitch angle, proton fluxes appear at a maximum near the 90° pitch angle; when the pitch angle is greater than 120° or less than 60°, the proton flux is almost zero. In addition, the proton flux in the main South Atlantic Anomaly region is completely anisotropic in each energy channel, and the proton flux in the sub South Atlantic Anomaly region tends to be isotropic as the energy channel increases. And this phenomenon is further verified by the NOAA observation data. Moreover, it is used to explain the formation mechanism of the sub South Atlantic Anomaly region.
