太阳风与火星相互作用是研究火星全球大气演化，深入理解火星全球气候环境演变的关键环节。研究表明，火星当前没有类似地球的全球偶极子磁场，太阳风直接与火星电离层相互作用形成全球性的感应磁层。如图1所示，太阳风携带行星际磁场与火星大气发生相互作用时，会产生火星感应磁层空腔结构。这一作用主要包括两个物理过程，一方面太阳风粒子受行星大气粒子的碰撞而减速，太阳风减速会使得行星际磁场在火星上游出现堆积和压缩。打个...

火星高层大气（包括电离层和热层）是理解整个火星大气演化的重要基础，是火星大气逃逸的重要来源，因此成为火星探测的重要目标，国际上相关空间探测机构已对火星电离层进行了多次探测，如火星快车（Mars Express）、火星大气和挥发分演化探测（MAVEN），“天问一号”。高层大气的周日或逐日变化受低层大气各种波动过程向上传播的影响，这种扰动影响在短时间尺度上已有相关的事件研究，但长时间气候学尺度的耦合过...
