Changing rainfall patterns in Western Sudan

Authors


Abstract

Rainfall series to 1986 have been examined for North Darfur and North Kordofan. Annual and monthly series are presented and analysed. Relatively dry conditions have persisted in this region since 1966 due mainly to a decline in rainfall during July, August and September, the critical months for the annual agricultural cycle. Changes in daily rainfall magnitude and frequency are examined for these four rainy season months. It is recommended that agricultural planning and government policies be based on recent meteorological patterns.
