Evaluation and adaptation of a regional climate model for the Horn of Africa: rainfall climatology and interannual variability.

The article presents a study on the evaluation and adaptation of the Abdus Salam International Center for Theoretical Physics version 3 Regional Climate Model's (ICTP RegCM3) ability to capture the rainfall patterns and interannual variation in the varied region of the Horn of Africa. It mentions that the evaluation of the simulated rainfall was conducted for the four alternative convective schemes including the Modified Anthes-Kuo, the Grell scheme with Arakawa-Schubert closure, the Grell scheme with Fritsch-Chappell closure and the Emanuel scheme. The study reveals that the Emanuel scheme captures best the rainfall patterns and the interannual variability. It suggests that ICTP RegCM3 model can be used to study rainfall processes and variability and downscale seasonal rainfall forecasts.
