Figure 5

From May to August 2006 (a) latitude-time distribution of 586 dagpm contour along 110°E~120°E averaged; (b) longitude-time distribution of 500 hPa geopotential height along 27.5°N~33.5°N averaged (unit: dagpm) (note: in (a), shaded areas represent the latitude-time distribution of OLR anomaly ≤ −20 W·m−2, while in (b), deep shaded areas indicate that potential height is greater than 586 and 588 dagpm region. The long-dashed line is the multiyear average of 586 dagpm line in both figures).
