From: Continuation of tropical Pacific Ocean temperature trend may weaken extreme El Niño and its linkage to the Southern Annular Mode

Figure 4

Observed composite anomalies of temperature, zonal wind and eddy momentum flux convergence of three extreme El Niños. (a) Zonal-mean temperature composites (colour shading) overlayed with the OND climatological temperature (contours). The colour shading interval is 0.2 °C, and the contour interval is 10 °C. (b) Same as (a) except zonal-mean zonal wind composites. The colour shading interval is 0.5 m/s, and the contour interval is 10 m/s. (c) Same as (b) except eddy momentum flux convergence composites. The colour shading interval is 0.1 m/s/day, and the contour interval is 1 m/s/day. Stippling indicates anomalies greater than 1 standard deviation (σ). The linear trend and the influence of the Antarctic polar vortex variability were removed from temperature, zonal wind and eddy momentum flux convergence data before forming the composites.
