Abstract: | Over the last 50 years magnetospheric research has transferred its focus from geomagnetism to space physics, or from inferring the intensity of extraterrestrial currents, through discoveries of the main plasma regions in the magnetosphere, to predicting the processes occurring in the entire solar wind–magnetosphere–ionosphere system. Relating advances in magnetospheric physics to the framework of substorm research, this review paper demonstrates that the “recent” space age since 1960s consisted of (1) an exploratory/discovery phase in which the magnetotail, the plasma sheet, and the acceleration region of auroral particles were identified, and (2) a phase of comprehensive understanding in which we have attempted to comprehend the nature and significance of the near-Earth space environment. This progress in solar-terrestrial physics has coincided with a number of new discoveries of solar and interplanetary phenomena such as magnetic clouds, coronal mass ejections and coronal holes. Computer simulation techniques have been developed to the degree that satellite observations from a very limited number of points can be used to trace and reproduce the main energy processes. We are now entering a new phase in which we hope to be able to predict the dynamic processes that take place in the solar-terrestrial environment. |
