Fig.5 Composite distributions of geopotential height anomalies (contours, Unit: gpm) and OLR anomalies (shaded areas, Unit: W·m-2) at 500 hPa in eastern Pacific type El Niño (a) and La Niña (c), central Pacific type El Niño (b) and La Niña (d) years (Green and purple lines indicate 5 880 gpm contours of the climatological mean geopotential height and the composite geopotential height, respectively. Dotted areas pass the significance test at the 95% confidence level for OLR anomalies; The characters “+” and “-” indicate positive and negative 500 hPa height anomalies, respectively) |
