我们回顾了地球表面扰动与高层大气耦合的观测结果。我们特别关注高层大气对脉冲地面扰动事件（包括地震、海啸、火山爆发和爆炸）中产生的大气声重力波的响应。本文综述了大气声重力波产生和传播的理论背景，以及电离层等离子体对这种声重力波的响应。我们回顾了各种观测技术，这些观测技术已经成功地用于探测由地表扰动引起的高层大气扰动，并总结了从这些观测中获得的关于耦合过程的最新知识。最后，介绍了该领域的最新进展，并提出了今后的研究方向。
We review observations on the coupling between Earth's surface disturbances and the upper atmosphere. In particular, we focus on the upper atmospheric responses to atmospheric acoustic‐gravity waves generated during impulsive surface disturbance events including earthquakes, tsunamis, volcanic eruptions, and explosions. We review the theoretical background for the generation and propagation of atmospheric acoustic‐gravity waves from surface disturbance events as well as of the ionospheric plasma response to such acoustic‐gravity waves. We review a variety of observational techniques that have been successfully utilized to detect upper atmospheric perturbations induced by surface disturbances and summarize the state‐of‐the‐art knowledge on the coupling processes learnt from these observations. Finally, we touch on some most recent advances in the field and propose directions for future research.
