CEDAR: Mesospheric and Lower Thermospheric Ducting of Gravity Waves Generated by Tropospheric Convection

小规模，对流强迫，管道重力波的特点是使用二维和三维非线性数值模型，比较模型重力波现象的数据，从海拔高度，重力波通常成像的目标。初步任务的特征结构，方向性，和影响的雷暴产生的重力波时，输送到中间层，并最终约87公里（气辉层）。第二个任务的特点大气中的“孔状”波的形态作为一种普遍现象，在一个理想化的大气。该通用模型的适用性观察中层孔进行了调查。最后一项任务是确定线性和非线性重力波现象如何扰动OI 557.7 nm和OH Meinel气辉层。

Small-scale, convectively-forced, ducted gravity waves are characterized using 2D and 3D nonlinear numerical models, with the goal of comparing model gravity wave phenomena to data from altitudes where gravity waves are commonly imaged. A preliminary task characterizes the structure, directionality, and effect of a thunderstorm generated gravity wave when ducted into the mesosphere and ultimately to about 87 km (the airglow layer). A second task characterizes the morphology of atmospheric "bore-like" waves as a general phenomenon within an idealized atmosphere. The applicability of that general model to observed mesospheric bores is investigated. A final task determines how linear and nonlinear gravity wave phenomena perturb both the OI 557.7 nm and OH Meinel airglow layers.
