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下风延伸到许多地球半径的磁场和气体（磁层），并产生数百万安培的电流，流经高纬度电离层，并产生引人注目的光发射显示，称为极光。该奖项旨在表彰使用雷达、光学和磁场测量设备来确定与电流和极光发射相关的电场模式，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.
