Interdecadal Variability of Summer Precipitation Efficiency in East Asia

Figure 5

Differences of column-integrated water vapor flux (kg/m/s/hPa) (a) and its divergence (kg/m²/s/hPa) (b), total precipitable water (mm/d) (c), precipitation (mm/d) (d), and precipitation efficiency (%) (e) in summer between 1999–2011 and 1983–1998. Thick vectors in (a) denote statistical significance at the 95% level. Solid (dashed) contours denote positive (negative) anomalies, and red (blue) color shadings from light to dark indicate statistical significance at the 90%, 95%, and 99% levels.
