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

综合测量温度，风和重力波结构在两个地点，山。夏威夷的哈雷阿卡拉和挪威北方的北极中层大气研究激光雷达观测站被用来量化中层和高层大气之间动量转移的关键参数。 重点放在量化的作用，重力波动力学的不稳定性，量化的动量输送和沉积，并确定平均强迫重力波在两个地区。 该方法包括激光雷达，光学干涉仪，成像仪和雷达的操作，随后的数值模拟，以允许量化的重力波振幅，平均流量和动量通量的不稳定动力学的响应。 在两个地点，一个极地和赤道的观测揭示了该方法的适应性非常不同的环境，或平均流量条件，部分由天气调制的区域。

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.
