Figure 7

Composite distribution of total rainfall, 850 hPa winds and AOD anomalies during different phases (P1 through P4, as defined by PC2) of the Asian monsoon intraseasonal oscillations for (a) P1, (b) P2, (c) P3 and (d) P4. Only positive values are shown for rainfall. Panels (e) through (h) are the same as (a) through (d), except for CO (ppbv) at 100 hPa, with geopotential height and winds at the same level superimposed. Likewise, panels (i) through (l) and panels (m) through (p), are the same as panels (e) through (h), except for CA anomalies (ppbm) and for dust anomalies (ppbm) at 100 hPa.
