EQUATORIAL DYNAMICS OBSERVED BY ROCKET, RADAR, AND SATELLITE DURING THE CADRE MALTED CAMPAIGN .2. MEAN AND WAVE STRUCTURES, COHERENCE, AND VARIABILITY/

We present an analysis of the wind and temperature measurements made b y rocket, radar, and satellite instrumentation in the equatorial and s ubtropical middle atmosphere accompanying the MALTED/CADRE campaign co nducted at Alcantara, Brazil during August 1994. Measured mean winds a nd temperatures extended from similar to 10 to 110 km, exhibited gener al consistency between instruments, and revealed an oscillatory nature of the mean zonal wind with altitude at equatorial latitudes. MF rada r measurements of tidal structures showed these to exhibit variability on similar to 8- and 16-day periods, but to be largely uncorrelated i n time. Two-day wave structures displayed the same periodicities, but were well correlated among sites at northern and equatorial latitudes. Rocket and radar measurements at smaller scales of motion revealed in ertia-gravity waves having significant temporal coherence, quadrature correlations between components indicating clear directions of propaga tion, and momentum flux and mean wind correlations indicative of gravi ty wave filtering processes. Rochet estimates of diurnal tidal amplitu des suggest that the diurnal tide achieves convectively unstable ampli tudes in the upper equatorial mesosphere.
