Additional file 1: Figure S1. Time series of GAIA zonal mean zonal wind averaged within 10°S to 10°N at altitudes of a 50 km, b 60 km, c 70 km, d 80 km, e 90 km, f 100 km, and its wavelet power spectra. Black dots indicate the location of maximum values within a period ranging from 1.5 to 3.5 years. Figure S2. Time series of GAIA temperature DW1 amplitude averaged within 10°S to 10°N at altitudes of a 50 km, b 60 km, c 70 km, d 80 km, e 90 km, f 100 km, and its wavelet power spectra. Black dots indicate the location of maximum values within a period ranging from 1.5 to 3.5 years. Figure S3. Time series of GAIA temperature DE3 amplitude averaged within 0° to 20°N at altitudes of a 50 km, b 60 km, c 70 km, d 80 km, e 90 km, f 100 km, and its wavelet power spectra. Black dots indicate the location of maximum values within a period ranging from 1.5 to 3.5 years. Figure S4. Time series of SABER temperature DW1 amplitude averaged within 10°S to 10°N at altitudes of a 50 km, b 60 km, c 70 km, d 80 km, e 90 km, f 100 km, and its wavelet power spectra. Black dots indicate the location of maximum values within a period ranging from 1.5 to 3.5 years. Figure S5. Time series of SABER temperature DE3 amplitude averaged within 0° to 20°N at altitudes of a 50 km, b 60 km, c 70 km, d 80 km, e 90 km, f 100 km, and its wavelet power spectra. Black dots indicate the location of maximum values within a period ranging from 1.5 to 3.5 years. Figure S6. Fourier spectra of DW1 amplitude and zonal wind from 2014 to 2016. Enhancement of GAIA temperature DW1 with a period close to 1.5 years during the 2014/2016 ENSO warm phase. a Fourier spectra of GAIA temperature DW1 amplitude averaged between 10°S and 10°N at various altitudes from 2014 to 2016. b Fourier spectra for the period of 2011 to 2013. c Altitudinal variation in the amplitude of the signal with the period of 1.5 years. d Relative difference between the two amplitude profiles as shown in e. Figure S7. Same as Figure S6 but for the SABER temperature DW1 amplitude between 10°S and 10°N. Figure S8. Same as Figure S6 but for the GAIA zonal mean zonal wind between 10°S and 10°N. Figure S9. a Fourier spectra of the U30 index from 2014 to 2016 and 2011 to 2013. b The difference between the two spectra shows an enhancement of the signal with a period close to 1.5 years.
