This study detects the El Nino Southern Oscillation (ENSO) events and signals, and the influences of the different ENSO stages in the rainfall of the dry zone in Sudan. Data from four meteorological stations were selected for analysis. Rainfall is found to be above normal during prolonged La Nina and below normal during prolonged El Nino. The ENSO event is examined in detail. Rehabilitation and establishment of new meteorological stations are crucially needed.enRAINFALLEL NINO SOUTHERN OSCILLATION PHENOMENONSUDANRAINFALLARID AND SEMI-ARID AREASLA NINA CURRENTADAPTATION TO CLIMATE CHANGEJournal Article (peer-reviewed)
