英文摘要: Atmospheric lunar semidiurnal tides are studied using 10 years of temperature data collected by the Thermosphere Ionosphere Mesosphere Energetics and Dynamics/Sounding of the Atmosphere Using Broadband Emission Radiometry satellite. The amplitudes and phases in the temperature field are calculated by performing least mean square fit in a data set of about 60 day interval (combining ascending and descending data together). The mean tidal structures are studied for the height range from 20 to 120 km, between ±50° latitude and centered on each month from February 2002 to January 2012. A clear signature of the 12.42 h (lunar semidiurnal tide) is observed in the data. Characteristic of propagating waves is observed in the vertical amplitude and phase profiles in almost all heights. The best conditions of propagation for the lunar semidiurnal tide are reached in the lower thermosphere region. Asymmetry between the hemispheres and seasonal variability is observed in the amplitudes of the tide. Longitudinal variations are also observed, which reveals the existence of nonmigrating components in addition to the dominant migrating lunar tide. Key Points The lunar tide achieves maximum amplitudes in the height of ionospheric E region The lunar tide presented an asymmetric behavior in relation to the equator The lunar semidiurnal tide showed a significant longitudinal variability ©2013.
