Symmetric and asymmetric enhancement of polar rain
From the examination of low-energy electron observed by DMSP-F2,-F3 and -F4 satellites and solar wind data obtained by ISEE-3 satellite, we found that there are two different kinds of polar rain intensification, which are characterized by symmetric and asymmetric enhancement in the two hemispheres,...
