Abstract

Trans-ionospheric high frequency (HF: 3–30 MHz) response to atmospheric gravity waves (GWs) is studied in the middle-latitude ionosphere in relation to thunderstorm activity. SuperDARN HF radar observations are compared against the model simulations to quantify the impact of GW-generated medium-scale traveling ionospheric disturbances (MSTID) activity on the skywaves traveling through ionospheric F-region heights. The tropospheric thunderstorm-driven convective source is modeled using MAGIC. The outputs are coupled with GEMINI to model ionospheric plasma response, which is then used to model SuperDARN HF radar observations using the PHaRLAP raytracing tool. Semi-concentric GWs were observed at different atmospheric heights, creating medium-scale traveling ionospheric disturbances (MSTIDs) at F-region heights. PHaRLAP raytracing through the modeled ionosphere shows qualitative agreement with SuperDARN daytime ground/sea scatter observations. Modeled rays show possibilities of long ducting Pedersen rays, suggesting MSTID can create a plasma waveguide to duct rays at the F-region altitudes.

利用SuperDARN高频雷达观测和模拟对流层重力波产生的MSTIDs对北美中纬度地区天波的影响

研究了中纬度电离层对大气重力波（GWs）的高频（HF: 3-30 MHz）响应与雷暴活动的关系。将SuperDARN高频雷达观测数据与模式模拟结果进行比较，量化gw产生的中尺度电离层扰动（MSTID）活动对通过电离层f区高度的天波的影响。对流层雷暴驱动的对流源用MAGIC模拟。输出与GEMINI相结合，模拟电离层等离子体响应，然后使用PHaRLAP射线跟踪工具模拟superdam HF雷达观测。在不同的大气高度观测到半同心gw，在f区高度产生中等尺度的行电离层扰动（MSTIDs）。通过模拟电离层的PHaRLAP射线追踪与superdam白天地面/海洋散射观测结果在定性上一致。模型射线显示了长管道Pedersen射线的可能性，这表明MSTID可以创建一个等离子波导来管道f区域高度的射线。
