图5 EP型El Niño(a)与La Niña(c)年、CP型El Niño(b)与La Niña(d)年500 hPa位势高度距平(等值线,单位:gpm)和OLR异常(填色区,单位:W·m-2)合成分布
(绿线和紫线分别为气候平均态和合成的5 880 gpm线,打点区域表示OLR异常通过95%置信水平的显著性检验,“+”和“-”分别代表500 hPa高度正和负异常)
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)
