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

这项研究将使用与UARS实验重叠的最近全球气候的水蒸气数据来更新日变化的日照率。这使得观测到的潮汐和模拟的潮汐之间可以直接进行比较。主要目的是阐明对流层加热对中间层和低热层中传播的日潮的季节和年际变化的影响。这项研究将使潮汐模型师能够从潮汐变化的其他机制中区分出对流层强迫，例如重力波阻力和平均风影响。PI的发现将大大有助于理解潮汐和中间层和低热层的全球平均环流的时间变化。

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.
