Abstract

This study investigates the large-scale ionospheric traveling disturbances (LSTIDs) over North America and Europe associated with the intense geomagnetic storm in May 2024, utilizing total electron content (TEC) data derived from ground-based Global Navigation Satellite System (GNSS) stations. The findings reveal that the observed LSTIDs in both regions exhibited an unusually prolonged duration, lasting for over 10 h from 17:00 UT on May 10 to 03:30 UT on May 11, 2024. This extended duration may be attributed to the continuous triggering of LSTIDs by auroral energy input during the geomagnetic storm. Additionally, significant differences in propagation characteristics, including velocities, azimuths, wavelengths, and traveling distances of LSTIDs, were observed between the two regions. These disparities in LSTID parameters are likely due to variations in the magnitude of energy input in the polar regions and local time differences in North America (14:00 LT) and Europe (19:00 LT), which cause diurnal electron-density contrast to influence LSTID propagation.

2024年5月极端地磁风暴期间北美和欧洲的大尺度电离层扰动

本研究利用地面全球导航卫星系统（GNSS）站点的总电子含量（TEC）数据，研究了与2024年5月强烈地磁风暴相关的北美和欧洲的大尺度电离层行进扰动（LSTIDs）。结果表明，这两个地区观测到的lstid的持续时间都异常长，从2024年5月10日17:00 UT到2024年5月11日03:30 UT持续了10多个小时。这种持续时间的延长可能是由于地磁暴期间极光能量输入持续触发lstid。此外，在两个地区之间，观测到lstid的传播特性（包括速度、方位角、波长和传播距离）存在显著差异。LSTID参数的这些差异可能是由于极地地区能量输入大小的变化以及北美（14:00 LT）和欧洲（19:00 LT）的地方时差异造成的，这些地方时差异导致日电子密度对比影响LSTID传播。
