Diagnosis of East African climate and the circulation mechanisms associated with extreme wet and dry events: a study based on RegCM4

Ongoma, Victor; Ogwang, Bob A.; Chen, Haishan; Tan, Guirong; Ntwali, Didier (Springer Berlin Heidelberg, 2015-05-22)

The latest version of the International Centre for Theoretical Physics (ICTP) regional climate model (RegCM4) is used in this study to examine the East African climate, focusing on October to December (OND) rainfall and ...
Dominant atmospheric circulation patterns associatedwith abnormal rainfall events over Rwanda, East Africa

Ngarukiyimana, Jean P.; Fu, Yunfei; Yang, Yuanjian; Ogwang, Bob A.; Ongoma, Victor; Ntwali, Didier (Wiley Online Library, 2017-05)

The study investigated the dominant atmospheric circulation patterns associated with abnormal rainfall overRwanda during the March–May (MAM) rainfall season in 1981–2010. The data sets used in this study include: rainfall,wind, ...
The impacts of topography on spatial and temporal rainfall distribution over Rwanda based on WRF model

Ongoma, Victor; Ntwali, Didier; Ogwang, Bob A. (2016)

The impact of topography on heavy rainfall during two rain seasons was investigated in order to explain their mechanisms on rainfall distribution over Rwanda. Weather Research and Forecasting (WRF-ARW) model was used to ...
