Figure 2. Composite anomaly maps, based on eight August SMI (Southwest Monsoon Index) extremes, of 500-mb heights (top, in geopotential meters) and precipitation (bottom, percentage departures based on 1946-1994 averages). |

Figure 3. Averaged 500-mb heights and anomalies (upper left and right respectively, in geopotential meters), temperature departures (lower left, in degrees Celsius), and precipitation percentiles (lower right) for August 1955. Temperature and precipitation are based on 1946-1994 data. |

Figure 4. Streamlines at 1500 m above sea-level (near 850-mb) and standardized humidity anomalies (percentages based on 1961-1990 averages). Bold numbers indicate humidity anomalies greater than ± 15%, with positive anomalies underlined. |
