在过去的二十年里，火星探测的爆发大大提高了我们对火星大气的了解。各种互补的多年观测记录揭示了火星系统中类似地球的尘埃和水循环，以及低层、中层和高层大气之间的动力学耦合，包括深对流、行星波、热潮汐和重力波，这些可以类似于地球大气中的耦合过程，但有时又非常不同。本文重点介绍了火星上几个涉及尘埃/水循环和波动活动的基本耦合过程：（1）低层大气中尘埃循环、水循环和波动活动之间的相互作用;（2）全球纬向环流和中层大气极地变暖;（3）尘埃/非尘埃条件下整个大气的垂直耦合。这些过程中的大多数已经研究了最先进的数值模型与最近的观察验证。此外，我们总结了几个新提出的假设，可能会影响我们的理解在行星科学的主要问题，如大气耦合，水逃逸，或中间层云的形成。我们发现地球和火星上的波致耦合之间有许多相似之处，地球的水循环和火星的尘埃循环之间也有相似之处，这为这两个行星的比较研究提供了见解。
The burst of Mars exploration in the past two decades has significantly improved our knowledge of the Martian atmosphere. A variety of complementary, multiannual observational records have revealed Earth-like cycling of dust and water through the Mars system, as well as hints of dynamical coupling between the lower, middle, and upper atmosphere involving deep convection, planetary waves, thermal tides, and gravity waves that can be analogous to, but sometimes very different from, coupling processes in the Earth's atmosphere. This review focuses on several essential coupling processes on Mars involving the dust/water cycling and wave activity: (1) interaction between the dust cycle, water cycle and wave activity in the lower atmosphere; (2) the global meridional circulation and middle atmospheric polar warmings; and (3) vertical coupling throughout the atmosphere during dusty/non-dusty conditions. Most of these processes have been studied with state-of-the-art numerical models validated with recent observations. In addition, we summarize several newly proposed hypotheses that potentially impact our understanding of major issues in planetary science such as atmospheric coupling, water escape, or mesospheric cloud formation. We find many similarities between wave-induced couplings on Earth and Mars and analogies between the Earth's water cycle and Mars's dust cycle, which provide insights into comparative studies of these two planets.
