The primary goal of this research is to achieve improved understanding of polar summer mesospheric dynamics and its coupling to the lower atmosphere. The methodology is based upon applying comprehensive data analyses to large ensembles of horizontal winds and gravity wave (GW) structures derived from the Aeronomy of Ice in the Mesosphere (AIM) satellite polar mesospheric cloud (PMC) observations. Horizontal winds will be derived using a cloud wind tracking algorithm applied to a full set of GW structures detected within each bowtie image of PMC forms. The cloud detection and GW analysis would be applied to the PMC measurements taken by the AIM Cloud Imaging and Particle Size experiment (CIPS) instrument (2007-current) for both northern and southern hemispheres (NH and SH). These winds would be validated in terms of monthly climatology or via coincidence comparisons for individual wind derivations. Undergraduate and graduate student participation is expected.Based on these results, two science objectives would be studied. The first objective would be the quantification of the occurrence frequency of GWs for each type of GW morphology. These results would be explored to determine possible GW source regions and to consider the wind filtering conditions that lead to either local GW excitation or the upward and poleward propagation of the GW event to the site of the observation. The other science objective is to study the fast traveling planetary waves (PWs) after correcting for the satellite aliasing effect. These PW events would allow the question of variability be examined regarding the inter-annual variability of the PW activity seen in the mesospheric winds and PMC albedo over the AIM mission period (2007-current). These results would also determine whether any inter-hemispheric tele-connection exists between the PW activity and the polar winter stratospheric vortex strength or temperature inside the vortex in the opposite hemisphere. Such a tele-connection would contribute toward understanding the details of the driving mechanism underlying the development of the polar summer PWs.

这项研究的主要目标是更好地了解极地夏季中层动力学及其与低层大气的耦合。该方法基于对源自中间层冰气学 (AIM) 卫星极地中间层云 (PMC) 观测的水平风和重力波 (GW) 结构的大型集合进行全面的数据分析。水平风将使用云风跟踪算法导出，该算法应用于在 PMC 形式的每个领结图像中检测到的全套 GW 结构。云检测和引力波分析将应用于 AIM 云成像和粒度实验 (CIPS) 仪器（2007 年至今）对北半球和南半球（北半球和南半球）进行的 PMC 测量。这些风将根据每月气候学或通过个别风推导的巧合比较来验证。预计本科生和研究生都会参与。根据这些结果，将研究两个科学目标。 第一个目标是量化每种类型的引力波形态的引力波出现频率。将探索这些结果以确定可能的引力波源区域，并考虑导致局部引力波激发或引力波事件向上和向极向传播到观测地点的风过滤条件。另一个科学目标是在校正卫星混叠效应后研究快速行进的行星波（PW）。这些 PW 事件将允许研究 AIM 任务期间（2007 年至今）中层风和 PMC 反照率中 PW 活动的年际变化的变化问题。 这些结果还将确定 PW 活动与极地冬季平流层涡旋强度或对侧半球涡旋内部温度之间是否存在任何半球间遥相关。这种远程连接将有助于了解极地夏季潜水道发展的驱动机制的细节。
