Detection of Migrating and Non-Migrating Atmospheric Tides Derived from ERA5 Temperature Meteorological Analyses

To better extract the tides represented in European meteorological analysis ERA5, an of histograms diurnal and semi-diurnal modes as a function longitudes was performed. This revealed that with different characteristics appeared regionally along single longitude. Retrieved migrating were compared tidal model showing global agreement below 60 km twice amplitude analyses at mid-latitude. Non-migrating have been identified tropical band. They logically appear above convective zones, probably due to water vapor excess. Their are from components. preliminary study has shown it is necessary develop additional observations allowing for more frequent sampling retrieve non-migrating can only be achieved satellite constellations space.
