Opposite Effects of ENSO on the Rainfall over the Northern and Equatorial Great Horn of Africa and Possible Causes

Figure 13

The difference of 200-hPa wind (streamline; left column), 850-hPa wind (vector in m s⁻¹), and rainfall (shaded in mm month⁻¹) (right column) in OND between El Niño alone and La Niña alone years (a, d), between pIOD alone years and nIOD alone years (b, e), and between El Niño and pIOD coexisting and La Niña and nIOD coexisting years(c, f). The magnitudes of wind are shaded in (a, b, and c). The red boxes marked in each panel represent the OND region.
