Altitude versus latitude structures of the W1 Q16DW amplitudes for the zonal wind (top), meridional wind (middle) and temperature (bottom) in January (first column), April (second column), July (third column) and October (last column). In addition, the monthly averaged zonal-mean zonal winds are plotted as contour lines (solid and dashed contour lines represent the eastward and westward winds, respectively, and the thick lines represent zero wind lines) in these months for reference, and the intervals of the contour lines are 10 \({\mathrm{ms}}^{-1}\)
