Figure 4
From: Surface Current in “Hotspot” Serves as a New and Effective Precursor for El Niño Prediction
SST averaged over El Niño (left) and La Niña (right) years during 1993–2015. Results in (from top to bottom) May, February-April, January-March, and January–February. Green contours: isotherms from 29.5 to 29.9 °C with an interval of 0.1 °C. Black contours: correlation r = 0.65 between N 7-N t and regressed surface currents over the southern hotspot shown in Fig. 2a, b, c and d. 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).
