Abstract. Sporadic E (Es) layers are patches of high ionization observed at around 100–140 km height in the region. Their formation low latitudes is primarily associated with diurnal and semidiurnal components tidal winds via ion convergence driven by wind shear mechanism. However, recent studies have shown influence other modes, such as terdiurnal tide. Therefore, this work investigates effect tide-like oscillations on occurrence Es over Palmas (10.17∘ S, 48.33∘ W; dip lat. −7.31∘), a...
Abstract In this work, the occurrence of different types sporadic‐ E layers ( Es ) was described for two stations located in region South America Magnetic Anomaly: Jataí and São José dos Campos. The results show hourly monthly values occurrences presented five (cusp, high, flat, low, slant), with flat/low f/l being most frequent over both stations. We also analyzed layer parameters blanketing frequency f b top t obtained from ionosonde data during storm‐time periods, order to investigate...
