Improved Seasonal Prediction of Rainfall over East Africa for Application in Agriculture: Statistical Downscaling of CFSv2 and GFDL-FLOR
Statistically downscaled forecasts of October–December (OND) rainfall are evaluated over East Africa from two general circulation model (GCM) seasonal prediction systems. The method uses canonical correlation analysis to relate variability in predicted large-scale rainfall (characterizing, …
Changes in Rainfall and Surface Temperature Over Lower Jubba, Somalia
Climate is changing at an alarming rate threatening the critical pillars for environmental, social and economic development. Signals of climate change seems to be quite real for many African communities. Somalia, is one the countries …
Tools and Procedures for Seasonal Downscaling of Climate Forecasts for Use by Farmers Over the Greater Horn of Africa: A Case Study for Western Kenya
Seasonal climate outlooks have become a necessary input to agricultural planning and execution of all farming activities as a form of adaptation to climate change and variability. Extended climate forecasts of 3–4 months pose a …
Temporal and Spatial Characteristics of the June-August Seasonal Rainfall and Temperature over South Sudan
Climate extremes including drought, floods, and high/low temperatures are recurrent in South Sudan and they are associated with widespread socio-economic miseries. This study aims at enhancing our understanding of past and present characteristics of climate …
Investigating the Homogeneity of Monthly Rainfall Records in Kenya
Homogenization of climate data is of major importance because non-climatic factors make available data unrepresentative of the actual climate variation, and thus the conclusions of climatic and hydrological studies are potentially biased. A great deal …
Empirical Relationships between Banana Yields and Climate Variability over Uganda
Variations in weather and climate have a significant impact on rain-fed banana yields in East Africa. This study examined empirical linkages between banana yields and variations in rainfall and temperature over Uganda for the historical …
Teleconnection responses in multi-GCM driven CORDEX RCMs over Eastern Africa
The ability of climate models to simulate atmospheric teleconnections provides an important basis for the use and analysis of climate change projections. This study examines the ability of COordinated Regional climate Downscaling EXperiment models, with …
Extreme Rainfall Assessment using Global Climate Models over the Greater Horn of Africa
The October to December (OND) is a major rainfall season over the Greater Horn of Africa (GHA) with strong El Niño Southern Oscillations (ENSO) signals and high rainfall variabil- ity leading to drought and floods. …
Oceanic and atmospheric linkages with short rainfall season intraseasonal statistics over Equatorial Eastern Africa and their predictive potential
Despite earlier studies over various parts of the world including equatorial Eastern Africa (EEA) showing that intraseasonal statistics of wet and dry spells have spatially coherent signals and thus greater predictability potential, no attempts have …
