图8 EP型El Niño(a)与La Niña(c)年、CP型El Niño(b)与La Niña(d)年850 hPa风场(箭矢,单位:m·s-1)和涡度(填色区,单位:10-5s-1)异常合成分布 (绿色箭头表示风场异常通过90%置信水平的显著性检验,打点区域表示涡度异常通过90%置信水平的显著性检验;字母C和A分别代表气旋和反气旋环流异常;灰色阴影区为高原地形) |
Fig.8 Composite distributions of wind anomalies (arrow vectors, Unit: m·s-1) and vorticity anomalies (shaded areas, Unit: 10-5s-1) at 850 hPa in eastern Pacific type El Niño (a) and La Niña (c) years, central Pacific type El Niño (b) and La Niña (d) years (The green arrows pass the significance test at the 90% confidence level for wind anomalies, dotted areas passes the significance test at the 90% confidence level for vorticity anomalies; letters C and A denote cyclonic and anticyclonic circulation anomalies, respectively; gray shaded areas are plateau terrain) |
