Effects of Aeolus wind assimilation on equatorial waves:
Kelvin Waves
Longitude-pressure diagrams of the zonal wind perturbations of the Kelvin waves in the OSE without Aeolus (NoAeolus) are shown by contours every +- 2 m/s. Solid lines show westerlies, and dashed isolines easterlies of the Kelvin waves, averaged within 5°S-5°N. Colour shadings show the difference between OSE including Aeolus wind and NoAeolus. Contouring is shown by the colorbar.

Hovmöller diagrams of the evolution of Kelvin wave zonal wind perturbations at 150 hPa and 200 hPa. Lines correspond to NoAeolus, with contours every +- 2 m/s. Solid lines show westerlies, and dashed isolines easterlies of the Kelvin waves, averaged within 5°S-5°N. Colour shadings show the difference between OSE including Aeolus wind and NoAeolus. Contouring is shown by the colorbar.
