abstract = "The structure, variability, and mean-flow interactions of the
quasi-2-day wave (Q2DW) in the mesosphere and lower thermosphere
during January 2015 were studied employing meteor and
medium-frequency radar winds at eight sites from 23 degrees S to
76 degrees S and Microwave Limb Sounder (MLS) temperature and
geopotential height measurements from 30 degrees S to 80 degrees
S. The event had a duration of 20-25 days, dominant periods of
44-52 hr, temperature amplitudes as large as 16 K, and zonal and
meridional wind amplitudes as high as 40 and 80 m/s, respectively,
at middle and lower latitudes. MLS measurements enabled definition
of balance winds that agreed well with radar wind amplitudes and
phases at middle latitudes where amplitudes were large and
quantification of the various Q2DW modes contributing to the full
wave field. The Q2DW event was composed primarily of the westward
zonal wavenumber 3 (W3) mode but also had measurable amplitudes in
other westward modes W1, W2, and W4; eastward modes E1 and E2; and
stationary mode S0. Of the secondary modes, W1, W2, and E2 had the
larger amplitudes. Inferred MLS balance winds enabled estimates of
the Eliassen-Palm fluxes for each mode, and cumulative zonal
accelerations that were found to be in reasonable agreement with
radar estimates from 35 degrees S to 70 degrees S at the lower
altitudes at which radar winds were available.",
