Figure 12

The difference of (a) 200-hPa wind (streamline), (b) 850-hPa wind (vector in m s−1) and rainfall (shaded in mm month−1), and (c) 850-hPa divergence (shaded in 10e6 s−1) in OND between positive IOD years and negative IOD years. The magnitudes of wind are shaded in (a). The red boxes marked in each panel represent the OND region.
