Wave dynamics of the mesosphere

大气中的波能够在大气层的不同层之间传递能量和动量。因此，如果我们想把大气作为一个整体系统来理解，那么理解这些波是非常重要的，在这个系统中，各层是耦合在一起的。在这个项目中，我们将使用五台雷达来测量中间层中的波，中间层是大气层中高度在55到100公里之间的部分。这些雷达位于从北极到南极的各个地点。我们特别感兴趣的是探测和测量强风吹过南安第斯山脉和南极半岛时产生的波浪，即所谓的“山波”。我们感兴趣的是了解这些波可以上升到中间层的条件，并计划确定它们对中间层大尺度风的影响。我们还将研究被称为平流层极涡的强烈、寒冷的冬季环流系统如何过滤和控制上升到中间层的波。我们计划参加一个重大的国际实验，SAANGRIA，与其他仪器合作研究这些现象。最后，我们将研究赤道中间层风如何控制行星尺度波的跨赤道传播

Waves in the atmosphere are able to transport energy and momentum between different layers of the atmosphere. Understanding these waves is thus very important if we want to understand the atmosphere as a whole system in which the layers are coupled together. In this project we will use five radars to measure waves in the mesosphere, which is that part of the atmosphere at heights of between about 55 to 100 km. The radars are located at sites ranging from the Arctic to the Antarctic. We are particularly interested in detecting and measuring waves generated when strong winds blow over the Southern Andes and the Antarctic Peninsula - so-called 'mountain waves'. We are interested in understanding the conditions under which these waves can ascend to the mesosphere and plan to determine the effect they have on the large-scale winds of the mesosphere. We will also study how the intense, cold winter circulation system known as the stratospheric polar vortex filters and controls waves ascending into the mesosphere. We plan to take part in a major international experiment, SAANGRIA, to study these phenomena in collaboration with other instruments. Finally, we will study how the winds of the equatorial mesosphere control the cross-equator propagation of planetary-scale waves
