Electrodynamics of Auroral Forms at Very High Latitudes

太阳风与受地球磁场限制的电离气体的相互作用导致磁场和气体(磁层)向下延伸到许多地球半径，并产生数百万安培的电流流经高纬度电离层，产生令人惊叹的被称为极光的光发射。该奖项是为了表彰使用雷达以及光学和磁场测量设备来确定与电流和极光发射有关的电场模式，以帮助理解在太阳风和磁层之间边界发生的物理过程。

The interaction of the solar wind with ionized gas confined by the earth's magnetic field results in a long extension downwind to many earth radii of the magnetic field and gas (the magnetosphere) and the generation of currents of millions of amperes which flow through the high latitude ionosphere, and create the striking displays of light emission known as the aurora. This award is for the use of radar and optical and magnetic field measuring equipment to determine the pattern of electric fields associated with the currents and auroral emissions, to help in understanding the physical processes that take place at the boundary between the solar wind and the magnetosphere.
