The amplitudes of different tides are shown in panel (a) for different days from January to March as obtained from the WACCM-X simulated meridional winds. Panels (b) and (c) show the phases and amplitudes of the quarter-diurnal and terdiurnal tidal components for the same duration, respectively. The bottom panel (d) depicts the change in wind magnitude after the post-sunset reversal in the wind. The shaded regions with salmon colour indicate the presence of wind reversal, and the magnitude of wind reversal can be seen to correspond with the amplitude of QDT. The blue shaded regions indicate the days when reversals were not seen, and the amplitudes of QDT were small. Reference lines have been marked for magnitude of wind reversal and maximum amplitude of QDT at the values of 25 and 16 ms-1, respectively. The phase of QDT, a reference line marked at 24 LT, also plays an important role. Whenever the magnitudes of wind reversal are greater than 25 ms-1, on most occasions, the amplitudes of QDT are greater than 16 ms-1 and phases are present at pre-midnight time.
