The unique climatic characteristics of the southwest tropical Indian Ocean. (a) Annual mean thermocline depth (D20) in the tropical Indian Ocean; (b) the longitude-depth cross section of sea water potential temperature along the 7°30′S; (c) the spatial pattern of point-to-point correlation between monthly SST and D20; (d) the spatial pattern of point-to-point correlation between SST and precipitation during April-May-June."

Scatter plot of the April—June SST anomaly in the southwest tropical Indian Ocean (2°30′—12°30′S, 50°—80°E) versus the previous winter (November to January) Niño 3.4 SST index (a) and the previous autumn (September to November) DMI (b). All the data were standardized. A red (blue) solid dot denotes a strong El Niño (La Niña) in the previous winter, and a red (blue) hollow dot denotes a weak El Niño (La Niña) in the previous winter"

Composited SST, surface wind, precipitation, and tropospheric thickness anomalies when strong April—June SST warming occurred in the southwest tropical Indian Ocean. (a) ~ (c) for SST and surface wind from April to June; (d) ~ (f) for precipitation from April to June; (g) ~ (i) for tropospheric thickness from April to June. Stippling denotes the composite anomalies passing the two-tailed Student’s t-test with a 90% significance level"
