Theoretical study on the magnetospheric distribution of up-flowing ions

Based on the dynamic equation, the static distribution function of the ions along the field line is found and features of density distributions of up-flowing ions along the field line are studied. The results show that, (1) the ion densities away from the Earth reduce more quickly in near geo-space,...

Description
Summary:Based on the dynamic equation, the static distribution function of the ions along the field line is found and features of density distributions of up-flowing ions along the field line are studied. The results show that, (1) the ion densities away from the Earth reduce more quickly in near geo-space, (2) the larger the ion mass is, the more quickly the ion density reduces along the field line, (3) when Kp=3∼5, the region that the up-flowing ions occupy is larger than that when Kp=0. Some results are consistent with the observation.
