Studies of Acoustic Gravity Waves in the Atmosphere

众所周知，声波-重力波普遍存在于大气层的各个层面。这些波受到各种来源的激发后，可以从对流层到热层，传播到大气层的各个层次，并可以在全球范围内传播很大的水平距离。由于这些波携带动量和能量，它们可能在决定中层大气的大尺度环流和热层与低层大气之间的耦合中发挥重要作用。世界声学重力波研究(WAGS)研究包括周期性活动，PI和他的同事参与其中。他们参加了1987年1月举行的关于WAGS的讲习班。他们将分析这些活动的数据，并对雷达波束和传播波的相互作用进行理论研究。其他理论研究课题包括重力波与大气涡旋的相互作用，例如在气旋扰动中发现的。重力波作为低层和高层大气之间的能量和动量耦合的来源，以及整个大气中的混合和湍流，正受到越来越多的关注。私隐专员公署和第一公署是该领域国际公认的专家。

The ubiquitous presence of acoustic-gravity waves at all levels of the atmosphere is well known. These waves, after being excited by various sources, can propagate throughout all levels of the atmosphere from the troposphere to the thermosphere and can propagate large horizontally distances on the global scale. As these waves carry momentum and energy, they may play and important role in determining the large-scale circulation in the middle atmosphere and in coupling between the thermosphere and the lower atmosphere. The World Acoustic Gravity Wave Study (WAGS) study involves periodic campaigns, in which the PI and his associates participate. They were involved in a workshop on WAGS in January 1987. They will analyze data from the campaigns and perform theoretical investigations on the interaction of radar beams and propagating waves. Other theoretical research topics include the interaction of gravity waves with atmospheric vortices, such as are found in cyclonic disturbances. The subject of gravity waves is receiving increased attention as a source of energy and momentum coupling between the lower and upper atmospheres, and of mixing and turbulence throughout the atmosphere. The PI and Co I are internationally recognised experts in the field.
