Introduction
My research is based on the Equatorial Africa climate system (Central African rainfall system/West African monsoon system). I focus on how Regional climate Models reproduce inter-linkages between precipitation and processes responsible for their generation. Also, I investigate how these inter-linkages will react to global warming.

Article
Full-text available
Two regional climate models (RCMs) participating in the CORDEX-Coordinated Output for Regional Evaluations (CORDEX-CORE) project feature a dipole-type rainfall bias during March-May (MAM) and September-November (SON) over Central Equatorial Africa (CEA), consisting in positive bias in West Central Equatorial Africa (WCEA) and negative bias in East...
Article
Full-text available
Improving the simulation of the West African Monsoon (WAM) system is paramount to increasing confidence in the projections of the region's monsoon rainfall change. This work aims to thoroughly analyze the representation of the WAM system in two state-of-the-art, high-resolution (~ 25 km) regional climate models (RCMs) in order to highlight the caus...
Article
Full-text available
Malaria is a critical health issue across the world and especially in Africa. Studies based on dynamical models helped to understand inter-linkages between this illness and climate. In this study, we evaluated the ability of the VECTRI community vector malaria model to simulate the spread of malaria in Cameroon using rainfall and temperature data f...
Article
Full-text available
Understanding real uncertainties in projections is needed to support actions of decision and policy makers. In this study, two state-of-the-art regional climate models with ~25 km horizontal resolution forced with three different global climate models are employed to investigate the response of the West African Monsoon (WAM) system under the low (R...
Article
Full-text available
Plain Language Summary Although the downscaling is proved beneficial for the African Coordinated Regional‐climate Downscaling Experiment domain, meaningful climate uncertainties persist; the origins of many biases/deficiencies in RCM results often remain unexplained, in a context where there is a requirement to ensure the fitness for purpose of the...
Thesis
Full-text available
Plausible climate information on future weather are needed to help policy makers in the adoption of resilience measures so as to constrain disastrous effects of changing climate. In regions with few available observed data like Congo Basin (CB), and where models feature the largest range of uncertainties, the confidence placed on a climate model pr...
Article
Full-text available
The results of a large ensemble of regional climate models lead to two contrasting but plausible scenarios for the precipitation change over West Africa, one where mean precipitation is projected to decrease significantly over the Gulf of Guinea in spring and the Sahel in summer, and the other where summer precipitation over both regions is project...

Article
Full-text available
In this paper, daily characteristics of the Central Africa rainfall are assessed using the regional model REMO in the framework of contributions to the CORDEX-Africa project. The model is used to dynamically downscale two global climate models (MPI-ESM-LR and EC-EARTH) for the present (1981–2005) and future (2041–2065, 2071–2095) climate under the...
Article
Full-text available
This paper studies sensitivity of Standardized Precipitation Index (SPI) to statistical distribution functions used in SPI computation procedure, in order to find out which are more appropriate and to assess SPI shift if using inappropriate distribution functions. Results may explain one of the reasons why spatial SPI computed with unique distribut...
Article
Full-text available
Understanding the processes responsible for precipitation and its future change is important to develop plausible and sustainable climate change adaptation strategies, especially in regions with few available observed data like Congo Basin (CB). This paper investigates the atmospheric circulation processes associated with climate model biases in CB...

Project
Assessment of precipitation processes and their variation in regional climate projections under global warming over Central/West Equatorial Africa.
Project
This project aims at giving a platform for new doctors in Water Science in Africa to present their CVs and profiles, and for senior researchers to find applicants for post-docs or full time positions in their institutions. IF you find this project useful and want to participate as a young doctor or a senior researcher in search of a young collaborator, please send me a message and I'll send you an invitation to join the collaborators of this project.
Project
This project led by Jean Jacques BRAUN (GET, Toulouse) and Bonaventure Sonké (Univ Yaoundé), funded by IRD, aims at bringing together scientists from France and Cameroon/Gabon mainly to study the links between climate and land use changes through the dynamics of vegetation cover and biogeochemical cycles.
