Amplitudes of temperature for different fit tidal modes and the zonal mean derived from the full PCM data for four cases: (a) South-Low-Clear, (b) South-Mid-Clear, (c) South-Low-Dusty, and (d) North-Low-Dusty. Panels (e)–(h) are similar to (a)–(d), but for the pressure field. The mode decomposition includes both tidal components and SPW contributions with the same zonal wavenumber.
