Short summary
This study investigates how tropical convection generates gravity waves, which play a key role in transporting energy across the atmosphere. By combining Aeolus satellite data with ERA5 reanalysis data and radio occultation measurements, we identified significant wave activity overlooked by ERA5, particularly over the Indian Ocean. Aeolus fills major gaps in wind data, offering a clearer picture of wave dynamics and challenging assumptions about their behavior, thereby improving climate models.
