CEDAR: Seasonal and Interannual Variations in Thermotidal Forcing by Water Vapor Insolation Absorption

这项研究将利用与UARS实验重叠的近期全球气体学的水蒸气数据更新日变化的日晒率。这样就可以直接比较观测到的潮汐和模拟的潮汐。主要目的是阐明对流层加热对中间层和低层热层传播日潮的季节和年际变化的影响。这项研究将使潮汐建模者能够从其他潮汐变化机制（如重力波阻力和平均风影响）中整理出对流层强迫。PI的发现将大大有助于理解潮汐的时间变化以及中间层和低层热层的全球平均环流。

This research will update diurnally varying insolation rates using water vapor data from recent global climatologies that overlap the UARS experiment. This enables direct comparison between observed and modeled tides. The main objective is to clarify the effect of tropospheric heating on the seasonal and inter-annual variability of the propagating diurnal tide in the mesosphere and lower thermosphere. This study will enable tide modelers to sort out tropospheric forcing from other mechanisms of tidal variability, such as gravity-wave drag and mean wind influences. The PI's findings will contribute substantially to understanding the temporal variation of tides and global mean circulations in the mesosphere and lower thermosphere.
