(a) Climatology and (b) composite vertical circulation (unit: horizontal wind m·s⁻¹, vertical p-velocity: 0.01 Pa·s⁻¹; vectors) averaged along 5°S–5°N between strong and weak APOI years. (c) and (d) are the same as (a) and (b), respectively, but averaged along 100°–120°E. Shaded values in (b) and (d) are significant at the 95% (light) and 99% (dark) confidence level.
