AB: We will examine the temporal variations of migrating diurnal tide in the mesosphere and lower thermosphere using the TIMED Doppler interferometer neutral wind data. The stratosphere QBO is the major source for the interannual variability of the migrating tide in the mesosphere and lower thermosphere. Buy examine the tidal variations using spectral analysis method, we plan to examine long term variations in the migrating diurnal tides beyond these related to the QBO. The TIDI data will allow us to examine the diurnal tide variation at different latitudes and altitudes. We will also study stratosphere observations in search of possible connections to changes in the stratosphere.
