Figure 3
From: Surface Current in “Hotspot” Serves as a New and Effective Precursor for El Niño Prediction
Surface current and wind stress curl averaged over February-April during 1993–2015. Left: surface current (vectors) and the zonal velocity (color shading). Right: wind stress (vectors) and its curl (color shading). Top, Middle and Bottom: the time-mean over all the years, and anomalies during El Niño and La Niña years, respectively. Pink contours: correlation r = 0.65 between N 7-N 4 and regressed surface currents over the southern hotspot shown in Fig. 2b. The figure is plotted using MATLAB R2015b (http://www.mathworks.com/). The maps in this figure are generated by MATLAB R2015b with Basemap (a mapping package, http://stockage.univ-brest.fr/~scott/MatLab/basemap.m).
