Drought has severe consequences for the livelihoods and economies of countries reliant on rainfed agriculture, such as Ethiopia. The Awash Basin, which experiences frequent droughts and water scarcity, requires effective water resource management. Identifying reliable drought indicators is crucial for early warning and mitigation. This study aims to determine the most relevant rainfall‐based indicator of historical meteorologi...

Purpose Eastern Africa has a complex hydroclimate and socio-economic context, making it vulnerable to climate change-induced hydrological extremes. This review presents recent research on drivers and typologies of extremes across different geographies and highlights challenges and improvements in forecasting hydrological extremes at various timescales. Recent Findings Droughts and floods remain the major challenges of the regi...

July-September rainfall is a key component of Ethiopia’s annual rainfall and is a source of rainfall variability throughout inland Greater Horn of Africa. In this study we investigate the relative influences of the Mascarene (MH) and South Atlantic (AH) highs on July-September rainfall in a covarying region of the Greater Horn of Africa using CHIRPS observed rainfall and the ERA5 reanalysis. We show that a mixed metric using t...

The purpose of this study was to evaluate the historical skill of models in the Coupled Model Intercomparison Project Phase 5 (CMIP5) in two regions of Ethiopia: northwestern Ethiopia and the Awash, one of the main Ethiopian river basins. An ensemble of CMIP5 models was first selected so that atmosphere‐only (Atmospheric Model Intercomparison Project, AMIP) and fully coupled simulations could be directly compared, assessing th...
