Supplemental Fig. 1 Name: equatorial_olr.eps
Supplemental Fig. 1. MJO Influence on ENSO Tropical Precipitation. Same precipitation
anomalies as in Fig. 1, but averaged 10°S-10°N and combined into a single figure. Red lines are
for El Niño composites, and blue lines are for La Niña composites. Statistical significance based
on monte-carlo resampling is indicated with shading, where the shading covers the 5%-95%
confidence range. (That is, any part of the lines outside the shading are significant at 5% or
better.
Supplemental Fig. 2 Name: enso_precip_allmon.tiff
Supplemental Fig. 2. Western Pacific Precipitation vs. Niño3.4 For All November-April
Months. The same data as in Figs. 4a and b, but for all November-April months, rather than just
those months with weak intraseasonal variability (Fig. 3a) or strong intraseasonal variability
(Fig. 3b), to show the general relationship.
Supplemental Fig. 3 Name: supp_fig_3.eps
Supplemental Fig. 3. Spatial Structure of Added MJO. The horizontal pattern of the MJO
activity that is added to the atmospheric, in terms of a) the standard deviation, and b) an example
of an individual phase. The idealized patterns are based on observed November-April variability
and the magnitude is set to be comparable to a strong observed event, such as January 2007. The
vertical profile of the added heating is a half-sine wave in the troposphere, consistent with deep
tropical convection.
