摘要：

By using the 2002-2016 dataset of COSMIC, CHAMP and GRACE radio occultation (RO) and TIMED/TIDI, we investigate the morphology of global sporadic E (E-s) layers and its relation with wind shear. The occurrence rate of E-s layers depends on temporal and spatial variation. The occurrence rate of E-s layers has a maximum at around 103 km in middle latitude regions in summer hemisphere. The results show that the global distribution of E-s layers is relatively consistent with the wind shear distribution. The height-local time distribution of E-s layers occurrences are primary modulated by diurnal and semidiurnal atmospheric tides. However, the distribution of E-s layers occurrence rate cannot be explained completely according to the wind shear theory, especially at equatorial and auroral regions. More observations are required to further investigate the formation of E-s layers and its relation with wind shear. (C) 2018 COSPAR. Published by Elsevier Ltd. All rights reserved.
