TL;DR: A new version of the RegCM regional climate modeling system, RegCM4, has been recently developed and made available for public use as discussed by the authors, which includes new land surface, planetary boundary layer, and air-sea flux schemes, a mixed convection and tropical band configuration, modifications to the pre-existing radiative transfer and boundary layer schemes, and a full upgrade of the model code towards improved flexibility, portability, and user friendliness.

TL;DR: In this article, the authors identified the oceanic regions that are associated with anomalous Ethiopian summer rains and the teleconnection mechanisms that give rise to these associations have been investigated and the results demonstrate that different mechanisms linked to sea surface temperature control variations in rainfall in different parts of Ethiopia.

TL;DR: The authors analyzed changes of four extreme hydroclimatic indices in the RCP8.5 projections of the Phase I CREMA experiment, which includes 21st century projections over 5 CORDEX domains (Africa, Central America, South America, Australia, South Asia, Mediterranean) with the ICTP regional model RegCM4 driven by three CMIP5 global models.

TL;DR: In this paper, the authors evaluated the performance of ERA5 reanalysis and document the progress made compared to ERA-interim for the fields of near-surface temperature and precipitation over Africa.

TL;DR: In this article, the quality of two NWP models, ERA-40 and NCEP reanalysis rainfall products, were evaluated for Kiremt and Belg seasons at a spatial scale that reflects the local variability of the rainfall climate using a method which makes optimum use of sparse gauge validation data.
