__________________________________________________________________________ Note: This is the normalized DMI from Mar1958 to Oct 1999. There are 500 values, one per month. We filtered off periodicities longer than 7 years (the decadal component) before calculating the index. We then applied a 5-month running mean to highlight the interannual component. The DMI is the difference of SST anomaly between the western (50 E - 70 E, 10 S - 10 N) and eastern (90E - 110 E, 10 S - Equator) Indian Ocean. The values given here were normalized by the standard deviation of the DMI. __________________________________________________________________________ Year Mon Normalized_DMI ----------------------
