Climate and climatic variability of rainfall over eastern Africa

Importance of the Indian Ocean for simulating rainfall anomalies over eastern and southern Africa

The relative contributions of the Indian Ocean and Pacific Ocean sea surface temperatures (SSTs) to the rainfall variability over eastern, central, and southern Africa during austral spring-summer are examined. The variability of African rainfall is statistically related to both oceans, but the variability in the two oceans is also related. To separate the effects of the Indian and Pacific Ocea...

Investigation of the atmospheric circulation anomalies associated with extreme rainfall events over the Coastal West Africa

This study investigates the atmospheric circulation associated with extreme rainfall events over the coastal West Africa. The rainfall data of this study were obtained from the Global Precipitation Climatology Centre (GPCC), spanning from 1981 to 2010. The atmospheric datasets were also obtained from the ERA-Interim reanalysis. The study employed the Z-Index to categorize dry and wet years into...

The nature of rainfall variability over Africa on time scales of decades to millenia

This paper begins with an overview of the African rainfall regime, noting in particular the contrast among various regions Ž . of the continent, followed by a description of the nature of climatic i.e., rainfall variability over Africa on time scales of decades and centuries. The decadal scale is examined using modern data covering the twentieth century. The century scale is examined using hist...
