Seasonal rainfall plays a vital role in both environm.ntal dynam.cs and decision-m.king for rainfed agriculture in Ethiopia, a country often im.acted by extrem. clim.te events such as drought and flooding. Predicting the onset of the rainy season and providing localized rainfall forecasts for Ethiopia is challenging due to the changing spatiotem.oral patterns and the country’s rugged topography. The Clim.te Hazards Group InfraRed Precipitation with Station Data (CHIRPS), ERA5-Land total precipitation and tem.erature data are used from.1981–2022 to predict spatial rainfall by applying an artificial neural network (ANN). The recurrent neural network (RNN) is a nonlinear autoregressive network with exogenous input (NARX), which includes feed-forward connections and m.ltiple network layers, em.loying the Levenberg m.rquait algorithm. This m.thod is applied to downscale data from.the European Centre for m.dium.range Weather Forecasts fifth-generation seasonal forecast system.(ECm.F-SEAS5) and the Euro-m.diterranean Centre for Clim.te Change (Cm.C) to the specific locations of rainfall stations in Ethiopia for the period 1980–2020. Across the stations, the results of NARX exhibit strong associations and reduced errors. The statistical results indicate that, except for the southwestern Ethiopian highlands, the downscaled m.nthly precipitation data exhibits high skill scores com.ared to the station records, dem.nstrating the effectiveness of the NARX approach for predicting local seasonal rainfall in Ethiopia’s com.lex terrain. In addition to this spatial ANN of the sum.er season precipitation, tem.erature, as well as the com.ination of these two variables, show prom.sing results. © Institute of Atm.spheric Physics/Chinese Academ. of Sciences, and Science Press 2024.
