| 目的 对临近空间大气中性风场进行监测与分析。方法 借助法布里-珀罗干涉仪（Fabry-Perot Interferometer，FPI）观测临近空间顶层的大气中性风场。针对北极黄河站（78.92°N，11.93°E）临近空间顶层的大气中性风场，介绍全天空 FPI 测风的基本原理，通过对 2016 年 11 月25 日全天空 FPI 设备观测的 OI557.7 nm 气辉干涉图进行分析，反演得到极光亚暴期间的内 5 级环的水平风场和视线风场。结果 极地地区临近空间顶层的水平风速基本保持在200~200 m/s 之间，极光亚暴使得中性风场呈现出一定的方向性，并且风场增大的方向垂直于极光弧。结论 利用全天空 FPI 设备可以对临近空间顶层的大气中性风场进行探测和分析，有助于认识和理解临近空间大气环境。 |

| Objective To monitor and analyze near-space neutral atmospheric wind field. Methods Fabry-Perot Interferometer (FPI) was used to observe the atmospheric neutral wind field of near space. For neutral wind field at the top of near space over the Yellow River station (78.92°N, 11.93°E), the basic principle of FPI has been introduced. OI557.7 nm airglow interferograms on November 25, 2016 were analyzed through the observation of all-sky FPI equipment. Horizontal wind field and visual wind field within 5 rings during auroral substorm were obtained through inversion. Result The wind speed of near space was kept between -200 m/s. and 200 m/s. Auroral substorms made neutral wind have certain direction. The wind field increased in the direction perpendicular to the aurora of arc. Conclusion All-sky FPI can be used to detect and analyze the near-space neutral atmospheric wind field, which helps to understand the near-space atmosphere. |
