This article briefly describes a paradigm shift in high-latitude space physics—a scientific revolution.This paradigm shift is a theoretical framework change from the electrical engineering(EE)theory to the magnetohydrodynamic(MHD)theory.Currently,this paradigm shift has proceeded relatively slowly,it is expected to fundamentally change our understanding of the magnetosphere-ionosphere-thermosphere cou-pling within in the next 30-50 years.
