  Hovmoller of OLR Anomalies from 2.5N to 15N

Time-longitude (Hovmoller) section of various OLR anomaly products averaged from 2.5N to 15N. Shaded are the 3-day running mean anomalies calculated by subtracting the climatological mean and smoothed seasonal cycle from the total field, where the mean and seasonal cycle were based on the 1979 to 1995 period. Contoured are the anomalies calculated by filtering the total OLR for the specific regions of the wavenumber-frequency domain defined in Fig. 1a or 1b. Note the close correspondence between the solid (negative) contours of the filtered fields with the yellow (negative) shading of the 3-day running mean anomalies, indicating the significant amount of variability of the OLR that is captured by the MJO and convectively coupled equatorial waves.
