这项研究的目的是了解一种称为中纬度持久风暴增强密度(LLSED)的现象的发生和发展。低纬电离层电子密度增强区是低纬电离层电子密度增强区,源自中纬电离层电子烟羽。“羽流”一词指的是地球磁层和电离层中的结构,它将这两个系统耦合起来,并在它们之间重新分配等离子体。LLSED持续时间超过6小时,比产生它们的SED羽流更长,并且可能对通信和导航系统产生不利影响。然而,对其原因仍未达成共识。这项工作巧妙地将地面和空间数据与数值建模工具相结合,以研究航空和电信行业所关注的电离层扰动。这笔赠款将支持一个早期的职业少数民族科学家,并有助于天主教U的REU计划。
英文摘要
The goal of the research is to understand the initiation and development of a phenomenon called mid-latitude long-lasting storm enhanced density (LLSED). LLSEDs are regions of enhanced electron density at low latitudes that emanate from midlatitude SED plumes. The term "plume" refers to structures in the Earth's magnetosphere and ionosphere that couple these two systems and redistribute plasma among them. LLSEDs last over 6 hours, outliving the SED plumes that spawn them, and can potentially adversely impact communication and navigation systems. However, there remains no consensus on their causes. The work skillfully fuses ground- and space-based data with numerical modeling tools to examine ionospheric disturbances that are of some concern for the aviation and telecommunication industries. The grant will support an early career minority scientist, and contribute to Catholic U's REU program.
