This project seeks to continue and extends investigations involving the energetics, dynamics, and variability of the low latitude atmosphere and ionosphere. The very general goals are to test, evaluate, and improve the NCAR upper atmosphere models; to use the models to investigate the effects of lower atmosphere waves on the thermosphere and ionosphere; to (attempt to) resolve some discrepancies between the observed and modeled upper atmosphere/ionosphere temperatures; and to investigate several selected topics such as the midnight temperature maximum, the behavior of the ion drifts, and the development of large neutral winds in the lower thermosphere.This project will continue the important task of validating the NCAR models, which are community resources with wide-ranging applications. The region of interest, the tropical ionosphere, plays an important role in global communications and navigation and is a major focus for space weather research. The project will support the research of a female space scientist/physics faculty member along with a graduate student.

该项目旨在继续和扩大涉及低纬度大气层和电离层的能量学、动力学和可变性的研究。 总体目标是测试、评估和改进NCAR高层大气模式;利用这些模式研究低层大气波对热层和电离层的影响;（试图）解决观测到的和模拟的高层大气/电离层温度之间的一些差异;并研究了几个选定的主题，如午夜温度最大值，离子漂移的行为，该项目将继续验证NCAR模型的重要任务，这些模型是具有广泛应用的社区资源。 感兴趣区域热带电离层在全球通信和导航中发挥着重要作用，是空间气象研究的一个主要重点。该项目将支持一名女空间科学家/物理学教员沿着一名研究生进行研究。
