abstract = "A comparative study of the quasi-16-day wave (QSDW) in the middle
atmosphere using meteor radar observations and reanalysis data
from three Brazilian stations, Sao Joao do Cariri (7.4°S S, 36.5°S
W) (CA), Cachoeira Paulista (22.7°S S, 45°S W) (CP), and Santa
Maria (29.7°S S, 53.7°S W) (SM) has been carried out in the year
2005 to delineate its latitudinal variability characteristics. The
broad spectral behavior around 16-day periodicity may indicate
multiple modes of the concerned wave component. The wave amplitude
shows a number of peaks over the year with the largest one in
summer and winter in the case of mesosphere-lower thermosphere
(MLT) and stratosphere, respectively. A potential coupling of the
concerned wave with other short period planetary waves, especially
at CA and CP is evinced. Although zonal propagation exhibits both
eastward as well as westward waves there is a general preference
of eastward waves at mid-latitude and westward waves at tropical
latitudes. The prevailing westerly background wind in the middle
atmosphere is conceived to favor the wave filtering of westward
propagating Rossby waves at lower latitude.",
