    Variability of seasonal and annual rainfall in the River Nile riparian countries and possible linkages to ocean–atmosphere interactions 

    Onyutha, Charles (Hydrology Research, 2016)
    Variability analyses for the rainfall over the Nile Basin have been confined mostly to sub-basins and the annual mean of the hydroclimatic variable based on observed short-term data from a few meteorological stations. ...

    Trends and variability in African long-term precipitation 

    Onyutha, Charles (Stochastic Environmental Research and Risk Assessment, 2018)
    African precipitation trends are commonly analyzed using short-term data observed over small areas. This study analyzed changes in long-term (1901–2015) annual and seasonal precipitation of high spatial (0.5 9 0.5 grid) ...

    How well do climate models reproduce variability in observed rainfall? A case study of the Lake Victoria basin considering CMIP3, CMIP5 and CORDEX simulations 

    Onyutha, Charles; Rutkowska, Agnieszka; Nyeko-Ogiramoi, Paul; Willems, Patrick (Stochastic Environmental Research and Risk Assessment, 2019)
    In this study, how well the climate models reproduce variability in observed rainfall was assessed based on General Circulation Models (GCMs) from phase 3 and phase 5 of the Coupled Model Inter-comparison Project, i.e., ...

    Contributions of Human Activities and Climatic Variability to Changes in River Rwizi Flows in Uganda, East Africa 

    Onyutha, Charles; Nyesigire, Resty; Nakagiri, Anne (Hydrology, 2021)
    This study employed Soil and Water Assessment Tool (SWAT) to analyze the impacts of climate variability and human activities on River Rwizi flows. Changes in land use and land cover (LULC) types from 1997 to 2019 were ...

    Space-time variability of extreme rainfall in the River Nile basin 

    Onyutha, Charles; Willems, Patrick (International Journal of Climatology, 2017)
    In this study, spatio-temporal variability in daily rainfall extremes based on 0.5∘ × 0.5∘ gridded data over the Nile basin was analysed using the quantile perturbation method. The co-occurrence of the extreme rainfall ...

    Analyses of Precipitation and Evapotranspiration Changes across the Lake Kyoga Basin in East Africa 

    Onyutha, Charles; Acayo, Grace; Nyende, Jacob (Water, 2020)
    This study analyzed changes in CenTrends gridded precipitation (1961–2015) and Potential Evapotranspiration (PET; 1961–2008) across the Lake Kyoga Basin (LKB). PET was computed from gridded temperature of the Princeton ...

    Trends and variability of temperature and evaporation over the African continent: Relationships with precipitation 

    Onyutha, Charles (Atmosfera, 2021)
    This study analyzes changes in the long-term (1901-2015) monthly values of potential evapotranspiration (PET), precipitation, and minimum (Tmin) and maximum (Tmax) temperatures across Africa to quantify trends and assess ...

    Assessing the spatio-temporal climate variability in semi-arid Karamoja subregion in north-eastern Uganda 

    Egeru, Anthony; Osaliya, Richard; MacOpiyo, Laban; Mburu, John; Wasonga, Oliver; Barasa, Bernard; Said, Mohammed; Aleper, Daniel; Majaliwa Mwanjalolo, Gilbert-Jackson (International Journal of Environmental Studies, 2014)
    Semi-arid areas show climatic variability on a spatio-temporal scale. There are few studies on the long-term trends and intensity of this variability from East Africa. We used National Ocean and Atmospheric Administration ...

    The Effect of Land Use on Carbon Stocks and Implications for Climate Variability on the Slopes of Mount Elgon, Eastern Uganda 

    Mugagga, F.; Nagasha, B.; Barasa, B.; Buyinza, M. (International Journal of Regional Development, 2017)
    We investigated the impact of land use change on carbon stocks and its implications to climate variability in Mountain environments. Remotely sensed biophysical data was used to determine the extent of land use change ...

    Vulnerability of smallholder sorghum farmers to climate variability in a heterogeneous landscape of south-western Uganda 

    Mugagga, Frank; Nakanjakko, Noeline; Nakileza, Bob; Nseka, Denis (Journal of Disaster Risk Studies, 2020)
    Smallholder farmers in sub-Saharan Africa are at a greater risk to the impacts of climate variability. We therefore sought to assess vulnerability of smallholder sorghum farmers to climate variability in Kigezi highlands ...
