Table 1 Comparison between LSWS features and the results from our study
LSWS features (Tsunoda 2005) | Atmospheric longitudinal variability on EPB-active days (our findings) | Similarity |
|---|---|---|
East-west shallow perturbation of ionospheric density | East-west fluctuation of temperature and wind velocity | Good |
Enhancement at equator | Large amplitude at lower latitudes across equator | Good |
Appears in afternoon to dusk period | Found at any time | Good |
Zonal wavelengths range from several hundreds to 1000 km | Zonal wavelength exceeded 2000 km | Inconsistency 1 |
Stationary to the ground | Eastward propagation | Inconsistency 2 |
