Collaborative Research: CEDAR: Quantification of Gravity Wave Instability Dynamics and Mean Forcing Using MTM and Related Instrumentation at ALOMAR and Maui MALT

两个站点的温度、风和重力波结构的综合测量。夏威夷Haleakala和挪威北部的北极激光雷达中层大气研究观测站(阿洛玛)被用于量化中高层大气之间动量转移的关键参数方面。重点是对重力波动力学中不稳定作用的量化，动量输送和沉积的量化，以及两个地区重力波平均强迫的确定。该方法包括激光雷达、光学干涉仪、成像仪和雷达的操作，以及随后的数值模拟，以便能够量化重力波幅度、平均流和动量通量上的不稳定动力学响应。在两个地点，一个极地和一个赤道的观测揭示了该方法对环境或平均流条件非常不同的地区的适应性，这些地区部分地受到天气的调节。

Comprehensive measurements of temperature, winds, and gravity wave structure at two sites, Mt. Haleakala Hawaii and the Artic Lidar Observatory for Middle Atmosphere Research (ALOMAR) in Northern Norway, are used to quantify key parameters aspects of the momentum transfer between the middle and upper atmosphere. Emphasis is placed on quantification of the role of instabilities in gravity wave dynamics, quantification of momentum transport and deposition, and determinations of mean forcing by gravity waves in the two regions. The methodology includes operation of lidars, optical interferometers, imagers, and radars, with subsequent numerical modeling to permit quantification of the response to instability dynamics on gravity wave amplitudes, on the mean flow, and on the momentum flux. Observations at two sites, one polar and one equatorial reveal the adaptability of the methodology to regions of very disparate ambient, or mean-flow conditions that are modulated in part by weather.
