9302258 Parish The purpose of the proposed research is to investigate electrodynamic coupling between the high and low latitude ionosphere during periods of raised geomagnetic activity and to study the dynamo effects of planetary waves in the lower thermosphere and their influence on the F-region ionosphere. These two areas of research will be addressed by analyzing measurements from ionosonde and magnetometer stations close to the geomagnetic equator and, for the electrodynamic coupling study, values of the AE index will also be analyzed. Spectral analysis will be performed on these data for the whole of 1979 and fluctuations with periods between a few hours and two days will be examined. ***

提出的研究目的是研究在地磁活动增强期间高纬度和低纬度电离层之间的电动力学耦合，并研究低层热层中行星波的发电机效应及其对f区电离层的影响。这两个研究领域将通过分析靠近地磁赤道的电离层探空仪和磁力计站的测量结果来解决，对于电动力耦合研究，也将分析声发射指数的值。将对1979年全年的这些数据进行光谱分析，并检查周期在几小时到两天之间的波动。＊＊＊
