Ionosphere irregularity
Web26 jan. 2024 · Irregularity motion is mainly observed along the Earth magnetic field line. Then the most likely reasons of amplitude distribution modality change are the variations of irregularity motion velocity and direction. WebField-aligned irregularity (FAI) in the E region is also observed by Very High Frequency (VHF) radar in mid-latitude regions. FAI frequently occurs after sunset in summer hemispheres, and spectrum features of E region FAI echoes suggest that type-2 irregularity is dominant in the nighttime ionosphere.
