Thermospheric Wind over Chinese Yellow River Station and Tromso during Auroral Substorm

  • 摘要: 中高层大气风场探测对研究大气物理过程具有极为重要的意义,尤其是在极地地区,风场对大气结构的影响更为剧烈.针对亚暴期间中国北极黄河站和日本Tromso站上空OI557.7nm气辉层(低热层)中性风场,利用全天空法布里-珀罗干涉仪(all-sky Fabry-Perot Interferometer,all-sky FPI)探测气辉谱线的多普勒频移,反演气辉层的大气风场信息.结果表明,低热层风场平均水平在100m·s-1左右,热层风场在极地地区更为剧烈,纬度相对较低的Tromso站探测到的风速整体小于同期黄河站上空的风速.结合离子风数据,分析离子拖拽和焦耳加热对中性风的影响过程,发现极光亚暴不仅对低热层风场有增强作用,也有明显的抑制效果,但整体风向都垂直于极光弧变化.
