Figure 4: Net surface cooling of 84 MJO pulses relative to 3RMM.
From: Ocean feedback to pulses of the Madden–Julian Oscillation in the equatorial Indian Ocean
Data represent pulses identified using reanalysis data products between 1980 and 2013, as described in the text. Of these 84 pulses (grey circles), 18 pulse pairs separated by <55 days are plotted with matching colours, each colour representing a pair of pulses. The first of the pair are denoted by circles, the second by triangles. Confidence limits are defined in the Methods. The pulse pair data are significantly and negatively correlated with r=−0.49 [−0.71, −0.20], P value=0.0022. The solid black line represents the regression δSST=−0.23 × 3RMM−0.2. The dashed black lines represent 95% confidence limits on the slope of the regression. Correlations, slopes and P values are not substantially different between the 84 parent pulses and the 36 paired pulses.
