Polar and auroral dynamics

我将从南极研究南极极光(南极光)。它环绕着南极大陆，尤其是白天的极光将接近头顶，这使得详细研究其与太阳活动有关的动力学成为可能。我将使用一台扫描光度计，它将在每个长达6个月的南半球冬季连续扫描子午线，穿过南极磁极和地理极，监测极光和气辉排放--以与我最近对北极帽和北极光的类似研究进行比较。我还将探索两半球极地高层大气的结构和动力学，以期进一步了解整个高纬度的全球环流。

I will be studying the Aurora Australis (southern lights) from the South Pole. It encircles the Antarctic continent and the dayside aurora in particular will be nearly overhead, enabling detailed studies of its dynamics in relation to solar activity. I will use a scanning photometer which will scan the meridian through the south magnetic and geographic poles continuously through each 6-month long austral winter, monitoring both auroral and airglow emissions- for comparisons with my similar recent studies from the northern polar cap and the Aurora Borealis. I will also exploring the structure and dynamics of the polar upper atmosphere  in both hemispheres with a view to gaining further understanding of the whole global circulation at  high latitudes.
