| Remote impact of winter (DJF) and spring (MAM) NINO3 on the fall (SON) mean volume backscattering strength (MVBS) through external climatic factors. (a) Fall MVBS anomaly (green bars) and averaged NINO3 anomaly (red line) for winter and spring. E and L on top of (a) indicate the decaying years of El Niño and La Niña events, respectively. Surrounding black circles mean that NINO3 and PDO are in phase and maintain their signs from winter to fall. (b) Composite maps of the averaged anomalies of surface solar radiation during the decaying fall of El Niño years (2009/10 and 2015/16). The figure was created using MATLAB (ver. 9.9.0.1592791 (R2020b) Update 5). The coastline is based on the ETOPO1 dataset (https://www.ngdc.noaa.gov/).
