From: On the variability of the seasonal scale oscillations over Cachoeira Paulista (22.7°S, 45°W), Brazil
Temporal variation of the monthly mean tidal amplitude and residual zonal wind. (a) diurnal tide amplitude and deseasonalized-AO (~SAO) wind, (b) diurnal tide amplitude and deseasonalized-SAO (~AO) wind, and (c) diurnal tide amplitude and deseasonalized (~QBO) wind. The dashed horizontal line denotes zero wind. Please see the text for details of the abbreviations.
