CEDAR Postdoc: Ionospheric Coupling to Atlantic Hurricanes and Tropical Depressions

该奖项支持博士后研究人员研究对流层扰动（如飓风和热带低气压）与低层热层/电离层区域之间的耦合。这项研究的目的有三个方面：1)观察飓风和热带低气压对f区电离层可能产生的影响；2)确定热带风暴是否会产生可观测到的重力波传播到热层；3)确定重力波或电场是否更有可能产生f区扰动。该方法是建立一个与风暴发生相一致的f区测量数据数据库。这项研究将使用在波多黎各阿雷西博天文台进行的电离层探空仪和非相干散射雷达测量。建立数据库后，将对f区扰动、相关热带风暴的相对位置和强度以及f区密度和电场的变化进行分析。了解电离层与其他大气区域之间的耦合有助于了解空间天气及其对技术系统的影响。

This award supports a postdoctoral researcher to study the coupling between tropospheric disturbances, such as hurricanes and tropical depressions, and the lower thermosphere/ionosphere region. The objective of the research is three-fold: 1) Observe possible effects of hurricanes and tropical depressions on the F-region ionosphere, 2) Ascertain whether the tropical storms produce observable gravity wave propagation into the thermosphere, and 3) Determine if gravity waves or electric fields are more likely to produce F-region disturbances. The approach is to assemble a database of F-region measurements coincident with storm occurrence. The study will use ionosonde and incoherent scatter radar measurements made at the Arecibo Observatory in Puerto Rico. After assembling the database, the data will be analyzed for F-region disturbances, the relative position and strength of any associated tropical storm, and variations in F-region density and electric fields. Understanding the coupling between the ionosphere and other atmospheric regions contributes to knowledge of space weather and its impacts on technical systems.
