Interdecadal Variability of Summer Precipitation Efficiency in East Asia

Figure 3

Normalized PC2 time series of the summer mean precipitation efficiency in East Asia during 1979–2016 (a), spatial distribution of EOF2 (b), and analysis of variance on PC2 variability (c). The percentage value at the top right in (a) denotes the explained variance of EOF2. Blue solid lines in (a) represent the abrupt change in mean value between 1979–1997 and 1998–2016, and the dashed line is the zero baseline. Significant PC2 variabilities in (c) are marked with blue asterisks.
