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

<div>Schematic diagrams showing the relationship of (a) JJAS rainfall and (b) OND rainfall in the GHA with tropical SST. The solid (blank) arrow represents anomalous (climatological) wind at 850 hPa. R+ (R-) marks the positive (negative) rainfall anomalies over the GHA.</div>
